that was wicked... though i doubt the b29 was up to scale. No way a scaled wing profile would have any lift when inverted....

Um... NO wing generates positive when inverted*. Any plane sustaining upside down flight is doing so through a combination of wing-lift generated via a relatively severe angle of attack and thrust. With enough thrust, you could have a completely flat wing capable of flying upright or inverted with no discernible change in the flight envelope.
*Okay, it does generate lift but in a direction which is pushing it and the plane towards the ground.

Well yeah, symmetric airfoils generate lift by tiling upwards (angle of attack increases). What I'm saying, though, is that theres virtually no way an asymetric airfoil scaled from a b29 could sustain itself inverted.

those are very cool. Loved the X1 blast off! Reminds me of that video with the R/C B-52 that crashed...unfortunate, but still very cool. Wish I had the money to get into r/c....
