In regards to the YL-15 being able to hold altitude with the nose both +25 degrees above the horizon and below anyone have any ideas on how it was able to do so? Being able to reflex the full length flaps no doubt helped. And 25 degrees nose up, hanging on the prop doesn't seem at all improbable, but what about 25 degrees nose down? Wouldn't that put the wings at a severe negative AOA regardless of the flap setting? And remember, the engine had 7 degrees of down thrust, so it's pulling even further downward.
I liked the column featuring John Crisp's Fokker DR1 representation.
