My goodness.. I've not seen so much wing flex in a long time. Soon after take-off the engine furthest away was truly wobbling, lol. However, for all the amazement, have to say that I love it. I always love watching the wing activity on a plane and it makes flying so much more 'real'. Aircraft engineering always fascinates me, starting with the fact that such a huge and heavy metal machine such as the B747 series (my favourite, even more than the A380) can lift off, fly and land so gracefully.

I've watched this video countless times and it remains my favorite takeoff vid. There is clear, visible evidence of several of the physical forces at play during the takeoff and climb-out phases of commercial flight. I think it's a great testament to the engineering that went into the 747-400. Plus the sound is very good. Love it!

Watch closely at 0:52 and 0:57 as the engines start to rise and the wing (also at 0:57) when the plane is holding. The pilot has the brakes on full and the engines at max!. This flight was fully loaded + cargo. You can tell the weight by the bounce that she takes at 1:30 as the wings are starting to flex up and down. They make teh plane jump a bit before the nose even starts to rise. THAT EQUALS A VERY HEAVY LOAD.. Great video and NICE camera work!

Hi! I don't know if there's some videos about, but it's also very impresive the flexing capability of a B-52 bomber wing. An old 50 years (or more?) design, you know. The 52's wings are very high located, and are so flexible that they need supports at its extremes, on ground.

Hi, it's not smoke, it's humidity. When the air is sucked into the engine, it accelerates very rapidly, causing its pressure and thus its temperature to drop dramatically, and this, in turn, causes the moisture the air contains to precipitate and become visible. this normally happens during takeoffs in hot and/or humid environment.

It's used as stability for the aircraft. At the speeds a plane is moving, the wings need to flex in order follow the patterns of the wind and keep the airplane from rolling in level flight. It's a very important part of the structure, because if the wings didn't flex and was fixed, the wind would cause the entire plane to move unpredictably and this would even cause fracture, which we don't want! :P

They are designed to bend more than that due to turbulence take off. Wings are designed to flex... if they do not flex they may snap like chopsticks. The pilot trust up first before releasing the brakes as you can see the engines pushes upwards as they spooled. What an beautiful and incredible piece of machines ever made by humans.

No, I understand that. I was answering the question about what gas was in the jet. Jetfuel is kerosene. But you are correct, that is condensation in the engines. I believe that it occurs when the temperature inside the engine is either cooler or hotter than the temperature outside and it also occurs in moist conditions as you said.

yeah, maybe he WAS actually talking about the aileron's and then Spoilers kicking in a bit, as the pilot rolls the yoke beyond a certain Degree. true. that's exactly what happens: when a certain "angle" of Roll is input at the control column, the Roll Spoilers ( Boards" as they're also called) pop up a little to Assist the Aileron's in effecting the Turn. What I was referring to, or thought he might have been talking about, were those LED's extended off the Leading Edge's. cool.

FruityLoosas, the wings are designed with a certain amount of flex in them. If wings were designed (and they could be) to be completely rigid, then they would snap under harsh landings, or extreme turbulence. The end of the wings are designed to flex upwards up to several meters without failing. The result of this is the "shaking" you see.

The lift off speed is dependant upon the weight of the aircraft. The heavier the aircraft the higher the speed. At maximum take off weight of 875,000 lbs (396,890 kgs) Vr (rotation speed) will be about 175 knots and V2 about 185 knots.

@futurer90 My *personal* feeling is: The bigger the plane, the smoother and quieter (and thus, more boring) takeoff and landing are. A 747 accelerates slower and more gradual than a smaller plane, thus you get less strongly pressed into the seat.

Haha yeah the flexing is normal.. in aerospace engineering we study it as a phenomenon called aeroelasticity.. to put it in perspective, the forces acting on the wing are greater than the weight of the airplane thats why its lifting off the ground, and all that force (we're talking over 400,000 lbs on each wing) causes the wing to bend upward. In addition since the flow field around the wing keeps changing the pressure distribution keeps changing so its flutters.

Great vid. Flaps/slats are brought in on 'schedule'. It seems obvious the plane was very heavy as the takeoff roll was long. after the initial climb it was probably accelerating fairly slowly, so it took some time between flap retraction steps. the main flaps would have been retracting during the climb but you can't see them. the Slats are the last to come in.

@HansensUniverse Thats the beauty of flying is wing flex. Just think of a diving board as it flexes when someone jumps off, the same applies to wings. They must be flexible to take on turbulence or if not, it'd break under pressure.
