Ron is making me think again!
Looking at the graphic, it strikes me kind of funny that folks stall on takeoff, and though I know of one fatal wreck that happened that way (test flight #1 in a Nieuport 11 replica), I am trying to figure it out.
Best I can reckon is that apart from test phase fun with engines, it's short fields doing the pilot no favors as he goes for too much max climb to clear obstacles that has to be to blame.
Any enlightenment?
