Ett av testflyene av den nye Gulfstream 650 har styrtet under takeoff og alle 4 ombord er bekreftet omkommet. Ulykken skjedde da ene vingen traff bakken da flyet akkurat hadde tatt av.

En tragisk ulykke og tankene går til de etterlatte

Interessant å lese hva NTSB mener var årsakene til ulykken:
The NTSB determines that the probable cause of this accident was an aerodynamic stall and subsequent uncommanded roll during an OEI takeoff flight test, which were the result of (1) Gulfstream's failure to properly develop and validate takeoff speeds for the flight tests and recognize and correct the V2 error during previous G650 flight tests, (2) the G650 flight test team's persistent and increasingly aggressive attempts to achieve V2 speeds that were erroneously low, and (3) Gulfstream's inadequate investigation of previous G650 uncommanded roll events, which indicated that the company's estimated stall AOA while the airplane was in ground effect was too high. Contributing to the accident was Gulfstream's failure to effectively manage the G650 flight test program by pursuing an aggressive program schedule without ensuring that the roles and responsibilities of team members had been appropriately defined and implemented, engineering processes had received sufficient technical planning and oversight, potential hazards had been fully identified, and appropriate risk controls had been implemented and were functioning as intended.

Oj, det var litt av en smekk de fikk der!
