Not really a problem cause the wings would rip off at about the same point in time
[:D][:D]
The reason i brought it up is i ran across that in my readings on the P-38. Because of the high-lift wings which were designed to give it a good climb rate, the air would move across the top of the wing at 40% faster than the bottom of the wing.
This means that at altitude (where the speed of sound is slower) that in a dive (say at 450 mph True Air Speed), the air would be moving at supersonic speeds while the rest of the plane is moving at 450 mph. This caused the infamous "compressability tuck" - and it could be difficult to get OUT of the dive if you didn't know what you were doing.
And yes, if you tried turning to get out of the dive, the wings COULD come off. However, a good pilot (even if untrained in the situation) could figure it out. For a green pilot - well, things were problematic.
IAS would be nowhere near what the True Air Speed was in these cases. All kinds of wild speed records were claimed by various pilots and touted in the papers.[:D]
