Dumping fuel is for multiple reasons. It lightens the plane for easier landing and, of course, removes fuel from a possible fire situation. This is one of the best approach and landing videos I have ever seen. Nice job.
Aaaaahhh .... How Sweet!! What an awesome day to fly (even though you had to return to LHR (??)! Multiple cloud layers to descend through; angle of the Sun gave great lighting; under cast; flying between layers; broken stato-cumulus layer on approach; for me, it doesn't get much better than this when photographing airplanes, or parts thereof. Great wing and engine shots. Thanks for the steady camera work, and the fixed focal length. Was able to pick out a few landmarks on final - Hyde Park being one of them; the Serpantine was easy to spot. Keep up the great work. Tony
Great video! That aircraft is about to complete 25 years flying next sunday. Amazing! Happy anniversary to her! =D BTW, engine 3 turned off probably to save as much fuel as possible since they had to throw most of it out. lol
Two questions, 1) obviously fuel dump to get landing weight is a big loss of $$ out the wingtips...so to they dump 'just enough' to get to safe landing weight thereby mitigating the $$ loss, or will they dump to a pretty low level for lightest weight (allowing for go around Im sure) - I mean in a controlled situation like this such as it is. And 2) for what seems to be a relatively non-emergent return to airport - do they tell folks that if they see fuel dump out of window thats normal, not to be alarmed etc.?
No, but I saw the Emirates Stadium and the old Highbury, then the London Stadium (West Ham United), then Wembley in the distance as we flew over Brentford's ground
Its my understanding that they had to throw 25 people off the plane in order for them to be at their maximum landing weight. Probably from economy I imagine. Is this true?
Where are they going to throw people off you can't open the doors on a plane in midair there pressured shut. And as no one knew this was going to happen they presumably had a full load onboard
On B747 they have pusher slats and they are retracted to kill the lift of the wing just as the airbrakes (spoilers) deploy. Other aircraft have push/pull slats that extend out of the leading edge of the wing. The B747 gets a very big lift area with their type of slats. The return out is just an automation as I understand it. They have to be manually retracted by the pilot out of this setting.
It's actually so debris or slush from a wet or snowy runway doesn't fly up into the le slats and cause damage or ice to freeze during thrust reverser deployment. Nothing to do with dumping lift. The spoilers do that.
+Fly757X I get that. But that's odd unless it's an unplanned landing. Airliners almost without fail carry just more than what's needed in fuel. It's calculated carefully. Dumping fuel is supposed to be in an emergency only.
+John Frakes Something wrong with the ventilation. Check out Dantorp's other video on the full flight. That's why it dumped fuel as it was a diversion.
+John Frakes there's a thing called maximum landing weight. to meet it and not having been flying for long when they made the decision to return to LHR they would have had to do a fuel dump.
It looked like the engine blades were spinning in the opposite direction now and then during flight; I thought they only do this with reverse thrust on the ground.
This has to be one of the best 747 videos that iv'e ever seen, thanks for the post.

Lmfao. Emptying fuel does not have to do with fire risk. It is 100% to reduce weight to below maximum landing weight.
Absolutely Stunning!!! I love the view of London!! Great Video, Your Content Continues To Amaze Me!
the camera work is crystal clear over here. nice work man
The quality of that video is awsome so sharp! Well done!
It does look like FTX EU England!!
Terrific video. London is always a good idea, even if you have to dump fuel to get (back) there.
Very beautiful. Thank you very much 👍
Another stunning video Dantorp, thanks for the time you put into making these quality videos. You should do a vlog soon ;)

Excellent flight footage as every time!
Awesome video mate!

Engine 3 is running it's the strobe effect of 25 frames per second that makes N1 not look like its spinning
+Paul Cook , you can actually see the moment it is turned off and it slowly stops spinning.
Great video, excellent job, Thanks much, enjoyed a lot.
nice view over Londen,thanks.
London
Why are my flight never interesting like this? :| but great video Dantorp as usual!
great footage, love when spotted wembley at 15:00 .
Saif Salama and at 14:04, Brentford FC ground at lower edge of video.
absolutely amazing
What's with the starboard inside engine? The intake ventilator seems off.
hey buddy you're verified!! congrats
Looks like the flight had gotten quite a ways away from Heathrow before the need to turn around was discovered..
so incredible
Shame we won’t be seeing the 747 very much now 😞
You can see the Wembley Arch at 14:24

If you noticed it wasnt very much, prolly a couple hundred gallons...this actually happens more than you would think on landings...
After landing why do the leading edge slats extend again at taxi speed? They cant be doing much at that speed.
Can you try to fly an SAS A330-300 from CPH to EWR?
Well, at least it was a three point landing.. Thanks...
What happend after that? Did they put you in another aircraft? O
Did you see Twickenham rugby stadium next to the Twickenham stoop were my favourite rugby team play harlequins and btw #COYQ
No, but I saw the Emirates Stadium and the old Highbury, then the London Stadium (West Ham United), then Wembley in the distance as we flew over Brentford's ground
You need to sit on the left side of the aircraft to see Twickenham.
very nice video thanks
Perfect!
they were dumping fuel in the air in the begining of the video
RR 917 no thats not dumping. its the water
They filled the fuel tanks with water? Is that what the mechanical problem was?
Gotta ask.. what turned out to be wrong to bring you back to Heathrow?? just curious
Ventilation problems.
Lovely video! Could anyone tell what is that open field on minute 14:55?
Osterley house and Park. National trust.
Pity that they're dumping fuel
Thats a hard landing
+Karebu219 It is the wind. I am not mistaken.
Its my understanding that they had to throw 25 people off the plane in order for them to be at their maximum landing weight. Probably from economy I imagine. Is this true?
Where are they going to throw people off you can't open the doors on a plane in midair there pressured shut. And as no one knew this was going to happen they presumably had a full load onboard
@@lorddarlo6194 Well I have it on good authority they threw off everybody in group 7 who refused to upgrade or enroll in a Miles Advantage account.
@@harrymallory7963 I can't tell of you are joking or being serious
@@lorddarlo6194 That much is obvious.
Not true. There were plenty of overweight Americans onboard, so they just threw out the five heaviest of them. That's what I heard.
Do you know why the slats were retracted and then re-deployed after landing?
On B747 they have pusher slats and they are retracted to kill the lift of the wing just as the airbrakes (spoilers) deploy. Other aircraft have push/pull slats that extend out of the leading edge of the wing. The B747 gets a very big lift area with their type of slats. The return out is just an automation as I understand it. They have to be manually retracted by the pilot out of this setting.
Thank you very much. That is interesting.

Thanks for the expanding info.
Thank you, that is most informative.
Hard landing
25 year old relic being flown by a US Flag airline that has seen better days. The air frame is probably fragile and it necessitated the fuel dumping.
Still better than 380
Might be a relic, but the 747 will always be the Queen of the Skies.
how is it better?
That view tho
What was the stream of smoke coming off of the wing?
Check out the full video + description of that here: ua-cam.com/video/8qIyDjmXqc4/v-deo.html
Dump fuel incase the landing went wrong
+xboxgamer no they dump some fuel because otherwise they're too heavy for a landing
Gotta dump fuel because they just took off and have a lot of fuel onboard and couldnt meet the maximum landing weight.
Also they dump fuel si if the landing does go wrong, the plane has less explosive fuel onboard
Did you film the landing at SFO?
It never made it there look at the description
Wow, Heathrow is far from downtown London.
No, Heathrow is in London !. just not Central London.
Yes, downtown London is what I was trying to say. Thank you.
It takes about 30 - 45 minutes to take a Heathrow Connect (non-express) train from Heathrow to Central London.
I guess that's not unusual. I live near Orlando and from OIA it takes about 45 min. to get to downtown.
Robert Dambeck Small world. I used to live in downtown Orlando! We moved from Florida about a decade ago. I miss International Drive!
I thought we already saw this one. Reposted.
Not the landing
Oh OK sorry.
I know why but so sad to see money is flying away at first ;_;
why are they dumping fuel??
+Fly757X I get that. But that's odd unless it's an unplanned landing. Airliners almost without fail carry just more than what's needed in fuel. It's calculated carefully. Dumping fuel is supposed to be in an emergency only.
+John Frakes they turned back because of a failure so it isn't a planned landing
+John Frakes Something wrong with the ventilation. Check out Dantorp's other video on the full flight. That's why it dumped fuel as it was a diversion.
+John Frakes there's a thing called maximum landing weight. to meet it and not having been flying for long when they made the decision to return to LHR they would have had to do a fuel dump.
dumping fuel is standard procedure.
It looked like the engine blades were spinning in the opposite direction now and then during flight; I thought they only do this with reverse thrust on the ground.
You have a lot to learn.
Hahaha
So maybe you are still in London to this day. Worse places to become a resident I suppose
united such a bad airline xD
just like every other airline
