Rotation Technique
Bravo the poster who mentioned the "JERKOFF" instead of a smooth rotation into a takeoff.
It is also called a "snatch" rotation. And except for certain, almost test flight situations, shouldn't be used.
And this goes for all planes , not just the Challenger.
I wish the FAA had observers at the end of all runways to perform an external wing check prior to takeoff, and if no good, no takeoff clearance. Same for other ICAO nations.
Feeling the plane's lift, sensing it, the heft in the stick, whatever you want to call it...is a lost art.
