Both wing fuel tanks were compromised and the aircraft was engulfed in fire. What We Learned... Impact was survivable, but cockpit/cabin environment deteriorated quickly due to fire.
22 lis 2012 · The crash occurred because the airplane stalled during one of these takeoffs. Gulfstream did not realize how much lower the critical angle-of-attack is in ground effect than it is in free air, and consequently the stall warning devices (stick shaker & pusher) were programmed to activate at too high an AOA.
