  1.  @stinkyfungus  Actually in real life I think Skyraiders attacked the bridge.

  2. The video is easy to misunderstand in a few places, but I don't believe it intended to say the wing was typical of the Me262. I believe it refers (perhaps unknowingly) to the 35-degree sweep proposed for a follow-on development of the 262 that was never built. The 18-degree sweep of the production 262 had not been implemented to increase the critical Mach number, but to resolve an issue with the center of gravity when the engines turned out heavier than originally planned. The DC-3 had about the same degree of sweep for the same reason. The video also seemed to be saying that the wing stalled from the tips at high speed rather than high AOA. Tip stall and compressibility are unrelated.

  3.  @Ernest-jr  The sweep angle of the XP-55 has nothing to do with compressibility and is there to provide stability, just like the wing sweep of flying wings or the Me-163. There is nothing wrong with the agility and stability of the 262. Slats have nothing to do with stability. Slats are nothing special and were in use before the Me262. The BF-109 had them. Many jet fighters had either slats or leading edge flaps for the same reason, greater lift and control at low speed. They are a high lift devices that remain in use in some airliners.

  4.  @Ernest-jr  You think you have accurate info on the XP-55, but you do not. What is "less agility" ? Of course the Me 262 had a larger turn radius than the slower aircraft to which those pilots were comparing it. That is natural function of speed, and is not a deficiency. Swept wings do not have "difficulties" near stall speed. Swept wings behave different than straight wings, and actually have some superior stall characteristics. The world has not gone back to straight wings for faster aircraft. Next time you fly on an airliner take a look at the wing. The F-86 had slats. It had nothing to do with high speed stability, it had to do with need for more low speed lift.
