The scariest sound on a plane is the sound the toilet makes when it flushes
Tru but a GE CFM56b isn't very scary
I get scared when i flush the toilet aswell
Fr
I get scared too
never flush it while sitting down, you know what happens right?
The most scary thing is when you don't hear the engine anymore.
The most scary thing is thatUA-cam just recommended me this
It’s just the pilot reducing the trust from initial takeoff power. Nothing to be worried about.
Oh ..
🤣 imagine sitting watching the wing then the engine just stops, hmm 🤔 perhaps these are new ultra quiet engines lol
Exactly, silence is a killer
Anytime I hear a strange noise while flying, I always look at the flight attendants. If they're acting normal, then I relax.
I got news for you buddy. They are trained to act normal even after they have witnessed the pilots yell “mayday we going down”
Yeah that’s true but In an emergency it’s not likely that they act normal In a stall or engine failure
Rali272 every single air disasters episode the survivors say they were terrified because they could tell the flight attendants were visibly paranoid
Mate there is training, and then there is real life
Fred L if you fly enough, especially in different aircraft, you’ll get used to the noise and turbulence.
For those interested, we normally do a takeoff at lower power setting on long runways to save fuel but then increase power after takeoff if for instance in a mountainous area. Max power on these engines are about 12 tonnes of thrust per engine.
Thank you for the knowledge!!
You have the best job in the world
@@slooob23 thanks so much! Was in IT for 10 yrs before I took the plunge and started the long road as a pilot
I am totally interested. Thanks very much for sharing
Very interested! I’m fascinated with airplanes!!
I can hear jeremy clarkson screaming POOOOWERRR in the distance

ROFL
TankBuilder Berlin I love u now no homo
Bene Plays no
You compared small b737 engine to huge 777 engine lol. Its like comparing fiat 500 engine with scania truck XD
Reduced thrust take off, long runway, reached 1000ft, climb thrust. Completely normal.
Not on my flights.
Increasing thrust after takeoff fails the smell test.
You’re probably right however. Lighter take-off weights will produce a planned power setting less than climb power.
When i see this, we select max power for takeoff.
@@shaark92 Piloting 101 - increase power in a turn (and keep the nose up) to prevent loss of altitude.
Could have been a noise abatement procedure with all those houses next to the field. He increased thrust as they were rolling into the left turn
@@nickbening4368 it's not easy to tell from the video ... but as I wrote ... using less than climb power for takeoff thrust is poor technique IMHBAO ... all you've done is artificially extend the take-off roll and the time susceptible to needing a reject.
Get airborne.
It appears the flaps/slats are still deployed, which isn't a bad idea for a steep turn out of traffic. Noise Abatements usually require max power on takeoff with a large power reduction in the second segment climb.
I'm not aware of any noise abatement which changes the 737 NG series normal takeoff/climb procedures anyway.
@@shaark92 What is a smell test? What are you smelling and what does the smell mean? How is it useful? Is it anything like how you can smell a hot car engine?
That sound is not scary...it is beautiful :)
Amen brotha
I thought this too :D Amen
mrhoffame it is
Yeaaaaa
totaly agree
It just went from reduced takeoff thrust to full climb thrust. Normal and it aounds lovely!
I love it when engines are at normal take off power then all of a sudden it goes into something like full power! It makes me feel weird inside... ...Lol!
Trey Pohe same
Im not an expert but from what I've learned from reading about take offs since i like reading about planes and such the thrust lever is first set to flex speed or i guess TOGA depending on weather weight ect...?? and the climb speed is set after takeoff. The climb speed on the thrust lever CL is a lower speed than Flex and TOGA so how can he set the speed to Climb (CL) after take off, planes do not take off on CL speed or lower than that and then increase thrust. Usually its flex speed or above not lower than that... unless I'm not understanding what you're saying and by full climb thrust you met from flex to TOGA?
Luca94 hey Luca, TOGA is the maximum rating of the engine for takeoff. The engine can only sustain that for 5-10 minutes. Usually however, to reduce maintenance on the engine we will "flex" the engine, providing some reduction from toga thrust. Up to 25% of total thrust may be reduced for takeoff. After passing a certain altitude (usually 1500' AGL) we will reduce thrust to climb power (which the engine can sustain indefinitely). However, when working with high flex reductions the climb thrust can actually be higher than the thrust used for takeoff. It's very counterintuitive but real. I was very surprised at the beginning when upon "thrust reduction" the thrust levers would actually move forward...
But that should have been the other way around full power @ the takeoff roll then once air born reduce power...
This was a low power takeoff, typically due to some combination of low weight and/or a long runway. At a certain point, usually 1000 or 3000 feet above the ground, the plane (with autothrottles) will automatically change to a climb power setting, which, in this case, was higher than the power used for takeoff, hence the engine acceleration sound.
Yes gorgeous what a sound. It's when you don't hear it that is scary
It's when they are full thrust and then they reduce it to what sounds like an idle (for noise abatement over neighborhoods); that's when I jump a bit.
@@mdaley4390 ? Your sort of correct. Planes take off on the runway and in 39s seconds into the flight they are already 3000ft. They will be at 10,000ft in about 2 minutes into the flight. Planes fly at 245 knots under 10,000 ft. They do not reduce the throttle. They keep it at 75% while increasing altitude. After 10,000 ft they level off their gain and start to gain altitude more slowly. They then make a left or right turn or continue straight. Then they push the throttle to 100% until they reach 340 knots. Some planes fly faster but no plane goes faster than 340 airspeed whitch is 540 knots ground and 600 mph.
Salvage Productions I like the reply, facts, but they don't throttle to 100% completely. They throttle to N1, the RPM at which is maximum to not possibly hurt the engine. Going over N1, for example 100%, can damage the jet engine. Also, it takes about 4 minutes to climb as planes typically climb out at 2500 after turning autopilot on.
Took off from an airport a few years ago that had heavy noise ordinances in the area. The flight crew made an announcement they would throttle back the engine shortly after takeoff to comply and not to worry if it suddenly got super quiet. Still a little jarring to hear full takeoff speed and then idle
delta9mda can I learn you some grammar?
It never fails to amaze me how that relatively tiny engines (to the fuselage) can lift up giant chunk of metal weighing hundreds tons
Gotta love physics
Indeed its physics for ya!!
Or aerodynamics
@@Tiggie2000 aerodynamics is based on physics
It amazes me how that relatively small wings (surface area to the fuselage) can lift up the entire aircraft. Its cool how on takeoffs they bend and sometimes 'flap' like a bird.
@@SwaggieBoss I had, what the seatguru-website called 'The Window Seat' on my first flight ever. Boy was I glued to the window as we experienced some clear-air turbulence and I saw that wing flap up and down ;)

I mean if both of ur engines fail when u take off you will crash as you wont be at cruising speed but at around 170 180 knots.
@@DaleSteel it's ok if your close to the ground and also close to water or an airport, its not ok if you're cruising and around a city without an airport or water nearby, well, I guess you could descend and while descending gaining speed along the way, although you're problem at that point would be finding a nearby airport or a water surface.

No that's a scary sound because you don't know if it's going to blow up or not
The reason why it sounds more humming like rather than a jet engine is because the tips of the blades break the sound barrier during 80%-full thrust
That explains also why mostly larger engines dont have this roar thanks
@@jansonb482 true true, never heard that in 747 or a380
Dc10s have it and its so gooood
Ever wonder why engines get quieter the higher you go. Because the air is less dense and sound can not travel as easily between molecules in the atmosphere
@@kylerider7125 True, but maybe also because you don’t apply full thrust while crusing
That's not scary, that's pure power.
Then the plane landed safely 45 minutes later.
They did a reduced take-off thrust (to save engine life time) Once in the air deleted redused thrust and got full thrust. Normal operation. Rgrds 737 pilot
Tks Fred, Ive always wondered if the pilots had miscalculated or something... :)
you are completely all right
They also do this for noise abatement in some areas.
Fredrik Lund Please explain why the need to go full power if the whole point in the 1st place was to prolong engine life and if they had a good rate of climb and airspeed.
737 pilot on FSX aye ;)
I'm 73 years old and I can remember my dad taking me to Idlewild (now Kennedy) airport to watch the first 707's take off.
Amazing engine sounds because there was no noise abatement crap then!
That's amazing
I love all those loud, smoky old turbojets and low bypass turbofans! That was music! The old JT3D makes my hair stand up!
mytmousemalibu
Reminds me of warthogs
amazing that there's an 73yo in UA-cam
I’m just reaching 60 and as an apprentice ‘cut my teeth’ training on the 707 and 720 series aircraft. Most had the beautiful sounding JT3D engines, some the pure jet JT3C. Aaaaah, those were the days 😊
I love that sound. :) They were probably headed in the direction of a strong tailwind or something and needed the airspeed to keep climbing. All that thrust is just awesome to hear though, the fact that humans can build such things is pretty incredible when you think about it.
No it’s called a reduced power take off , 99% of take off climbs are reduced to 1000 feet above the ground to reduce heat stress on engines , making them last longer . I do them just about every takeoff in the 737-700 I fly . Very safe and calculated.
Jim Anderson called thrust reduction?
@@kaiblue5660 This is called a derated takeoff
I was pleasantly surprised to come look at ther replies and not see people telling you that's bullshit. I used to reply to these kinds of videos (being a commercial pilot myself) and just got tired of folks arguing with me over something they knew nothing about. You're 100% correct.
Rogue Aerial Productions so when the engine gets louder at that threshold im assuming its because added power, some say its because they reduce power some say they add power. Im just a student pilot and avnerd wanting some straight answers lol.
@@kaiblue5660 definitely adding power as they clear the noise abatement area.
I fly a lot. This is a normal sound in older aircrafts. Order a rum and coke, play your favorite movie on your iPad and enjoy the flight.
I wish I had your flying mentality 🤷🏻♂️😂
I hate this noise, the planes I flew with in the last couple of years had a much quieter engine.
Hahha that is the way to do it!! 👍
As easy as that
737 700 is not old this pilot has a bad hangover or something.
The pilot is using the full thrust nothing to be scared about.
Jonathan yah fr
Using full thrust on takeoff is normal but it never sounds like that 😂
X BrainyBanana X i don’t see anything different from other max thrust good ol roar 🐯
flyingeagle357 the runway was probably short maybe overweight luggage
flyingeagle357 it is usual . When a plane is empty they don’t need to put full thrust

Why TF an Angolan captain would do this
This is why I don’t want future aircraft to have quiet engines
ChickenPlayzGamez exactly, who the hell wants that?! There best sound is when aircraft goes from zero to max power like on takeoff or go-around
ChickenPlayzGamez That is a fact,
Go live by an international airport or military base... By the end of your first year you will want out. Luckily the only reason why this 737 didnt go blasting out was for that very reason of people living by the airport so there are sound requirements
ChickenPlayzGamez well the future is sooner then you think the a320 neos are super quiet
Captain Earls its 50% throttle up then 50%-80-90%
This is probably one of my most favorite sounds that come from a plane just the power sounds so nice
Probably just hit the nitrous button..... then jams 3rd. gear into the turn. Lucky he didn't loose it.
Lol
I'm dead thank you! lucky he didn't lose it hahahahaha
XD
robbiehobbs2009 he didn't double clutch like he should
He wasn't granny shifting
anyone else get goosebumps from the Pure power into that thrust! WE HAVE LIFTOFF
the reasoning may be because the stalling speed dramatically increases during a high angle of attack medium turn so they add more power to keep it at a constant rate of climb.
That's because they did a Flex takeoff power. (reduced) and once they put CLIMB power, the engine rised up RPM.
A CLB power setting can be lower than the derate or the same as the derate, but CLB settings are never higher than the take-off derate. This was intentionally powered up most likely to keep it out of a hairy situation
Stephen correct and Incorrect. In a 737 NG you can select a Derated takeoff either TO1 or TO2 in combination with assumed temperature along with manually preselecting full climb thrust (although it will default to match the corresponding derate with a climb derate as you have correctly stated and will result in n1 decrease) but if you have a derate and assumed temp together thats big enough will usually result in an N1 increase at the thrust altitude if full climb thrust is preselected on the N1 page of the CDU. Preselected Full climb thrust has been a SOP at many airlines for many years for many reasons. One of main ones being climb derates mean a less efficient climb and more time in dense air burning fuel. Ryanair for example manually cancel any climb derate when cleared to any flight level above FL150 by ATC for this very reason. Other airlines like norwegian have been doing non derated climbs for a long time now. There plenty of youtube cockpit videos displaying this and would be happy to link some. Hope this helps!
gfusion you learn something new every day. Thank you!
This is the best flight video i have ever seen with the engine sound so realistic and loud ...happy to hear those engines...Cfm56-7b rockzzz
What a sweet, sweet sound. Absolute workhorse
they did a flex takeoff. its a reduced power takeoff, then resumed normal power in the climb.
The scariest thing is when the captain forgets that his on mic and says "huh whats the engine doing".
GTFO_ PIIKA 😂😂😂😂😂
The scariest thing is during surgery when the surgeon says "oops"
That "roar" is the turbofan fan blade tips breaking the sound barrier, if you sit behind the wing you won't hear it. At some airports they are required to quickly climb and turn for neighborhood sound abatement.
Planes add power when turning tightly - it keeps the plane from stalling in the turn. That engine sound is your friend. Love it.
It’s just climb thrust; an increased power level. The more angle of bank, generally you need more power to maintain your speed and retain airflow.
That never gets old…put out some good power right there 😎
It is common practice in jet airliners to use the minimum amount of takeoff thrust that is required to get safely airborne and clear the obstacles on climb out. The temperature changes that occur in the engine during takeoff are considerable; using less than full rated thrust on a regular basis has the benefit of reducing engine wear and increasing the engine's life-span. On Boeing aeroplanes, this reduction is known as ATM - Assumed Temperature Method (Flex Takeoff on Airbus). On the 737, once you have entered your assumed temperature, the FMC will automatically select a climb thrust that will become effective at 1000-3000ft (Thrust Reduction Altitude). The climb thrust will always be either the same as takeoff thrust or slightly less. However, many airlines have an operating procedure that recommends selecting the maximum available climb thrust in order to reach cruise altitude more quickly. Climbing to cruise altitude in the shortest time possible will result in a lower overall fuel burn because the engines will spend more time operating in the altitudes were they are most fuel efficient (approx 30,000 - 41,000ft). As a result, at 'Thrust Reduction Altitude' you end up with a thrust increase as the engines spool up to their maximum rating.
Takeoff thrust was rated lower than climb thrust, can happen in Boeing aircraft as they do not do FLEX takeoffs (see Captain Joe's explanation)
Shankovich wait so when Boeing planes retract the thrust in curising, what do the retract to? Or they dontV
I love that sound of PURE POWER. I already love car engines roaring, but this is AWESOME
What an awesome sound! I love sitting over the wing or engine at the window on flights!
Just sat right next to GE90s for the first time in my life recently. Can't explain how much I loved hearing them roar.
It’s not scary, it’s beautiful
I say the engines were increased to around 97% thrust power on 1:32. I’d say pilots never would go up exactly 100% or slightly over it due to increased wear and tear on the engines which can lead to dire consequences
Typically the Only time would be like an emergency last minute go around. I’ve been on a few of those, I think 4. One was a moose walked in the runway at the last minute, another one was for some pilot in a Cessna that puttered onto the runway at the last moment i don’t recall the reasons for the other ones
1:31 best sound i have EVER hear!
Yves Jahn but its still running lol thank god
I agree. I love the engine roar. I think that video of a 707 take off will change your mind.
I get off on this...
no its not.....the TF-39 that were on the c-5 galaxy is the best sound EVER
Yves Jahn sorry but a Merlin spitfire engine is the best engine sound.
The "roar" you hear is primarily aerodynamic noise from the high lift devices. Notice how it gets significantly quieter when they are stowed. The extendable landing lights (if this aircraft has them, newer NGs don't) make a lot of noise, too. The power setting on climb sounds typical to me.
This is the best 737 engine spool I've heard today. And I've been searching a lot!
It's called a flex temp; wherein pilots use less than full power to take off, thereby reducing noise, engine wear and maintenance costs.
Note: Flex temp is a term used for Airbus and Fokker airplanes. Considering Taag has an all-Boeing fleet, it can also be called reduced take-off thrust, or factored take-off thrust.
Mount Dracula yeah but they dont normally increase in power, normally it drops shortly after takeoff
LochVids depends, if using a high assumed temperature the thrust in CLB passing accel height can often be higher than D-TO. Especially on airlines that don't used fixed de rates but just assumed temps, take for example British Airways. Completely normal.
LochVids , well it all depends on a number of factors: takeoff weight, runway length, temp, density altitude, wind speed/direction, noise abatement requirements, reduction of engine wear, and probably other things I don't know about. But takeoff power and climb out power are carefully calculated before the flight takes off.
well i knew about flex temp but not about the fact that its only airbus
and also arent moat fokker aircraft being retired
Listen to the engines sing, good stuff.
Great catch! Would you be okay with me featuring this in my series Weekly Dose of Aviation? Of course you will be credited both in the video and in the description. Thanks!
ATC probably told him to expedite climb due traffic. Reduced power takeoff is routine stuff!
Mott Hoople It's climb thrust higher than takeoff thrust, can happen in Boeing aircraft as they do not do typical FLEX profiles
I've heard the same on an Airbus also - A330 series...
It reached its acceleration altitude, so the engines power increased. The acceleration altitude most of the time lays around 3000 ft, depends on the country and type of aircraft..
I love the sound of jet turbines at full thrust.
Tackz One 707 and 717 sound way better.
@Žiga Vrbanjac Yep! 80-85% depending on conditions.
Too bad this isn't a real jet turbine. It's a dustbuster that swallowed too many steroids. Yes it is technically a turbine engine, but this is a turbofan. Like all modern passenger aircraft. The roar of a real turbo jet isn't allowed anymore. When I was a kid, you heard the old JT8D engines at taxi power (20-40%) 4 miles away. I grew up 2 miles from the airport. I could hear the 727's taxi to the runway in my bedroom. If the wind was out of the east, the takeoff roll made the windows shake. Back then, jets were loud! The last time I visited the old neighborhood you didn't hear ANYTHING. I asked my old neighbor if the airport was even still in operation. I couldn't get over the fact that you can't hear anything anymore.
Annoying sound for me
It's not actually the engines making the high-pitched whine or buzzing sound, it is some metal parts of the aircraft resonating to the engine noise.
When I hear the engine, especially if it’s a cfm it makes me even calmer because Ik everything is 100% okay
the scariest part and y’all can’t lie is when during takeoff sometimes it feels like you are dropping and you can’t hear the engine anymore
Plastic E it’s usually when you reach cruise or reduce the climb rate. At both times, the plane usually requires less power.
*most-fun part
This has nothing to do with the age of the aircraft. Here, the takeoff thrust (most likely derated, also FLEX in Airbus terms) is lower than the initial climb thrust.
Boeings allow the aircraft to have such a configuration. Hence, the increase in thrust for climb results in a louder pitch. An Airbus, on the other hand, would instead bump up the takeoff thrust to match the initial climb thrust.
Great footage of the wing flexing upwards as the speed increases.
This is music to my ears. I’d be so happy to hear this.
when i was in Luanda at a friends house, i always heard these 737-700s roaring out of there. they seem to always takeoff at full power
What's scarier is when the pilot throttles down the engines to slow down and it briefly sounds like the engine is shutting off
My man listen, when the engines are shutting off you will know immediately by physics
This is normal... sometimes TO thrust is actually lower than climb thrust
that sound is AMAZING!!!
I fly about two to four times a year. That’s not a lot. However it’s enough to not be able to decide if I like the sound of this engine or not 😂
That's normal engine noise the 737-700, 800 and 900 have variable engine settings to save fuel on takeoff rotation to use as little power possible, then throttles up at 2000 ft for maximum climb
Ryan Hodge it is actually to reduce turbine temperature which in turn reduces wear and tear on engines. Fuel efficiency is gained at the higher flight levels. On a very hot day the engines are temperature restricted (EGT/TIT) and on a colder than standard day they are EPR restricted.
Music to my ears! I love they sound. Great video.
1:31 I've been on a few flights, and I've never heard a turbine throttle *increase* after V1... Wow, awesome.
Only once for me, and I have been on about twenty 737/A320 flights. The flight for me was Lisbon to London on an A319. TAP.
Pilot probably saw the speed goin down a couple o knots and deciced to jam the throttle
Pilots were not paying attention to airspeed probably and was fixated on ground speed, then realized they were close to stall airspeed and went full throttle.
i reckon the pilot just wanna try max thrust see what will happen
I suppose each individual has different experiences. Imagine that. I've been on plenty of flights that were like this. That's why I was like, "What's scary about this?"
The only issue I have with this particular engine noise is that it always makes my ears feel like they're going to bleed if I'm not wearing ear protection. Thank goodness for Bose noise cancelling headphones.
HOLY S**T The power from the engine is crazy. Especially when it makes that turn.
Amazing.
Not when I shift into MAXIMUM OVERDRIVE!!
Ulrik Ruud Rostrup time to kill the party. Overdrive lowers the revs so that you save fuel and reduces the need of another gear, it is good for highway driving. So what u wanna say is, “Not when I turn off MAXIMUM OVERDRIVE!!” lol

I don’t know if this makes me weird, but i love the feeling of a plane taking off and landings as well
Damn, three weirdos here.
This is very common. The aircraft is loud because it is banking and needs the extra power to maintain altitude. Also that humming noise is so nice.
One of the most frightening times for me include a flight from Indianapolis to Denver on an American Airlines 727, yes 727. The pilot took off at roughly half power, the wing slats were not deployed. Shortly after take off, the plane started to go into a stall. The vibration was strong. Then the pilots went to full take off power and deployed the slats until the plane reached the speed point where the flaps and then the slats can be retracted. Another time on a Delta flight in a DC-9 30 from Atlanta to Charlotte, on a very hot July afternoon, the pilot took off without the flaps and the slats deployed. How we stayed in the air amazed me, espeecially on a hot day when air density is low compared with air at 70 degf.
Stall? You sure?
High angle of attack plus high angle turn requires boogie.
The best answer in all of the comments! Boogie stops it falling back to earth! You must be a Pilot.
I too love to boogie. But that's because I love the nightlife 😉🎶 ua-cam.com/video/umAurdHLNzU/v-deo.html
From reduced thrust TOGA to Climb power , it happens automatically, it’s not because angle of attack or bank angle.
@@brucesn6414 hai i think its more rpms then the toga thrust i think its windshear warning in this case you go full thrust
@@brucesn6414 FMC AND VNAV CONTROL THAT
The reason why its roaring is because your placement of your seat, when your in front of the engine, it makes more noise. Also as the 737-700 is an older aircraft, this noise is normal
Those noises are music for an aviation enthusiast 🖤✈️
To the ones who are concerned about why the airplane takes off not with full power, it is simple. Lower fuel consumption and avoiding engine damage over long periods of time and after repeated start-stop engine cycles.
And noise abatement standards for populated areas.
@@ironnads7975 not necessarily. The sudden acceleration is at a rather low altitude but this could be evident in other real life scenarios like Sydney or London Heathrow at night.
mentour pilot did a great episode on this. it's completely normal for the engines to suddenly get quiet OR to suddenly get louder shortly after takeoff. it's supposed to happen on most flights.

fish295 Only CFM-56 that I know of. Source: Retired FAA certified A&P mechanics from when I was in school for aviation maintenance.
@@fish295 proof?
Most of the sound that you hear, is the conducted vibrations from the engine to the fuselage, causing the plastic panels to vibrate. FYI - the aircraft took off with reduced power for noise abatement, and once high enough, advanced the power setting for a faster climb.
If it was generating all that vibration during the video then the engine would be at risk of catastrophic failure due to lack of balancing. The sound is actually the tips of the front fan blades traveling quickly enough to break the sound barrier, people call it the "buzz saw" sound. Very common on older turbo fans.

Seems TOGA was enabled.
I mean you can't expect the pilot to reduce the engine power immediately after take off
That isn't the issue...the issue is the pilot increased thrust after the plane was about 1 thousand feet off the ground. Sometimes planes aren't at full throttle at take off due to noise restrictions.
@@ironnads7975 It's not often they're at full throttle at takeoff. They only use what's necessary, based on air temp, humidity, weight and others. They have the ability to call on the extra thrust if needed.
@@ironnads7975 Noise abatement is only one of the reasons for de-rated takeoffs
Retired 1011 Heavy mechanic - that's a perfect sound like the purring from a kitten. The engine was overhauled and finely tuned.
It would have been scarier if you said 737 max instead of max power
get out
I believe it was to compensate in speed for the sharp turn.
fcr855 nope. This is called a engine derated takeoff. The N1 CLB is higher as the takeoff thrust and as soon as the Autothrust switches to N1 CLB the Engine Spools up. It’s mainly a Boeing feature. Airbus sometimes do it as well when they use a low Engine Flex setting (mostly when it’s really hot ouside)
terry melvin yeah no...
Did it at any point stop?
engines always sound and perform the best right before they blow up lol
