arcdu...a piper cub can stall and the recovery is the same as any other plane.
lots of things caused the colgan crash
lots of things caused the air france crash.
it wasn't so very long ago...well maybe it was...I didn't get a regional job with less than an ATP and more than 1500 hours. It has been only recently that you could get an airline job with 300 hours or so and be placed into the right seat of a regional jet or advanced turboprop.
becoming an airline pilot is quite hard...and maybe it should be, it weeds out some people who won't give flying their all.
