1. 9 40mm hits to a M16 before it blows up, 2-3 40mm hits to a aircraft before it goes down
2. tests show that the guns are not set a 0deg of inclination. (30 ft of drop at 1k and stopwatch timed at 3 seconds of flight. should have greater drop)
3. plane tail drifts into ground while pointing gunsight at tank at low level. the way they had the gunsight and guns setup was so that this WOULD NOT happen due to the method they used to tank bust.
as well, the b17 can still up from a carrier with 3k of bombs.
