“It felt like you were climbing to the top of a roller coaster. It was at that point,” Williams said. “There were a number of screams on the plane. Everybody knew that something was out of the ordinary, or at least that this was not normal.”

The plane then went into a “dramatic, nose-down” dive for about eight to 10 seconds before it climbed steeply again and resumed normal flight.

飞机似乎以一个陡峭的角度爬升并失速,然后它俯冲下降,幸运的是它恢复成功(脱离失速速度并重新获得高度).

我的问题: 是飞行员失误还是机械问题??!
