Flight that killed former White House official pitched violently after takeoff

The business jet flight that killed a former White House official earlier this month violently pitched up and down after pilots addressed cockpit warnings by switching off a system meant to keep the aircraft stable, but it did not encounter turbulence as was initially reported, federal investigators have said.

Though board officials had said the day after the accident that there was severe turbulence when the plane pitched, the pilots told investigators they had actually not encountered any turbulence, according to the report published Friday.

Hyde, 55, was flying from Keene, New Hampshire, to Leesburg, Virginia, with her husband, Jonathan Chambers, and one of her sons, who was visiting schools. The three passengers were reportedly thrown around as the plane convulsed.

No one else was injured.

The two pilots in charge of the Challenger 300 where Hyde was mortally injured had a combined 13,000 hours of flying time and were rated to fly for airlines.
