    ★★★ *FACT UPDATES / ANSWERS TO FAQ's* ★★★
    *1) I said in the video "The Russian Antonov"* - The Antonov was not made in Russia, it's Ukranian made by Antonov Design Bureau, a Ukrainian aircraft manufacturing and services company.
    I think I originally heard the title of the plane "Antonov An-124 Ruslan" and heard Russian not Ruslan, and thought it was Russian from that moment on. My mistake.
    *NOTE TO ALL FACT CHECKERS ON MY VIDEOS* : I appreciate the feedback and the enthusiasm with which you like to fact-check informative and educational videos. Please understand that I am new to this format of video. I know I have gotten some facts wrong at this early stage of trying this format, I will try harder for future videos.
    To be clear, I do not know much, if anything, about the airplane industry, and I don't claim to be any kind of expert. What I was trying to do with this video, and others like it, was to answer questions that multiple people asked me in the comments of one of my videos. I have been doing this for over eight years on another channel, and I started this new channel to try going in a new direction.
    So bear with me while I try to improve.

      Yes, it is a technical thing after the fall of the erstwhile U.S.S.R. else it is okay to call it Russian too.
      Appreciate you keeping it brief yet informative.
      And as a non native English speaker.. i was reasonably happy that I did not have to rewind much or have to keep captions ON for most part.. except technical terms.
      You pace, clarity, diction was easy to understand.. for me at-least. Although I am a bit dumb to figure out the region/part of the world such accent is from.
      It surely is not from North America (U.S.) as it was much more clear.
      It would eventually help to add manual subtitles.
      I and others can help you with them.. if ever you feel like trying to add subtitles in any of the south Asian languages (Hindi Urdu Tamil Telugu Bangla Malayalam and so on).
      Appreciate you taking up a topic which even the regular aviation channels do not really speak of.
      Or maybe they are too focused on what can quickly make money for them and so they create such content.
      You put enough research and editing tine to intersperse the video with relevant clips, animations. THAT in my view was worth looking for in the future too.
      At my age and routine.. i obviously do not have that much leisure time on the internet.. but such content made with sincere efforts and without over the top hyper-animated voice or fake enthusiasm is always appreciated by me at-least.
      Maybe in the years to come you too would look at things more commercially with intro, outgoing, plug-ins and sponsors.
      Will try to be there then too, if i am alive.

    @3:35 as a pilot, i can tell you that "undulations" on the runway don't matter much, the overall slope may affect takeoff and landing distances, but that's all counted for in our calculations. when it comes to "enhanced vision systems" or EVS, this is not something you'd find in any airliner. At least for the time being, this is only in private jets, military and general aviation aircraft, and it's not meant to see undulations on the runway. It's designed for low visibility operations, and in some cases spotting wildlife on the runway when landing in remote areas.

    The Antonov shown has six engines and a twin rudder so this is a An-225, not an An-124 which has a boring four engines and single rudder. Only one complete An-225 did exist early in 2022 which is when the aircraft was destroyed in the Russian-Ukrainian war. Due to the age of the aircraft you might also call the aircraft Soviet. It was designed and built by the USSR for the Buran space program and was the Soviet equivalent to the US Boeing 747s modified as shuttle carriers.
    Wavy runways can be a bitch when you're a new pilot. They can also be a bitch at night when there is a hump in the middle which for the pilot of a small aircraft can make it impossible to see the end of runway lighting at the far end.

      @@manifestgtr Heh, I had a feeling my previous posting had the potential to be missunderstood. What I meant is that four engined stuff is pretty standard and thus boring. Six engined aircraft are rare and these days none of the types I know of (An-225, XB-70) is still flying.
      I started flying a bit too late so I missed the opportunity to see some interesting aircraft such as the SR-71 operating from near my home airfield. Though 747s were being serviced, the more common types of larger aircraft were all types of Citation which were being serviced by the company operating the airport or Hercules some coming from pretty far even outside NATO which came for special conversions. Other fun stuff was when for training purposes the PAPIs were switched to 5.5° so pilots could train approaches to London City without scaring the living daylights out of their passengers. Or once the Frankenhercules with two different types of engines. Three standard ones and for testing purpose the # engine had been replaced with a prototype of the future powerplant of the A400. Did look really odd because its much larger. Or the last airworthy Vulcan bomber XM558 on its first flight after the Vulcan to the Sky restored its airworthyness. With the boss of my flying club in the cockpit. Or the Red Arrows. But sadly no An-124.

    I have landed at Birmingham airport several times aboard an Emirate's A380 and each time it was a really hard landing. After seeing the wavy photos I did wonder if the pilot had lined up for a dip but touched down on a high spot.
    Landings at Heathrow and Dubai are a lot softer aboard A380s, so still wondering????
    Having worked in road construction where we graded high spots and filled low ones. With special attention to backfill compaction up against bridge abutments. Soft spots are removed and filled with suitable material from a burrow pit.
    That sadly doesn't happen in Vietnam where I now live, new roads have huge dips either side of the many river and streams bridges along there routes. When traffic has to slow right down to a near stop action is taken to fix them. They are then filled by laying several layers of asphalt with staggered ends cut into the road surface to feather the joints.

    I think you could have also added that it is not as simple as flattening the runway alone... for planes I am sure you can not have an elevated or lower tarmac than the dirt around it. Planes in emergency want to use the ground around the tarmac.
    So to make a runway flat, you would need to flatten the whole surrounding area as well. This makes the work super expensive.

    Lamding planes on short runways isn't a problem. Planes usually land with plenty of runway to spare, and that's without using maximum braking. There is even a case where a medium sized soviet airliner landed in a field (it was withdrawn and being delivered to it's final resting place). The big problem is taking off. There are cases where planes have landed ot airports with short runways, either due to an emergency or mistake, and getting them moved has been very difficult. In one case they had to empty the plane as much as possible, and put just enough fuel in to get it to the correct airport (which was only a few miles, hence the confusion), just to get it back in the air. Again, most planes will get off the ground with plenty of runway to spare (often around half way), but that extra runway is needed incase of an engine failure, either to stop or to get off the ground.

    Manchester Airport runway, well the original one before the second runway was completed, has a noticeable hump in the middle as could be seen on one of my photos taken from the co-pilots seat of a small twin engine plane. Probably this was more noticeable being sat closer to the ground. No doubt not so obvious from the lofty heights of a 747 cockpit. Bembridge Airport on the isle of Wight dips in the middle from either end. One of the pilots landing us there said you had to be careful otherwise the plane starts to lift off slightly half way down the 800 metre runway when you are landing.
