They fly the plane downward, matching the vertical acceleration with the acceleration caused by gravity.
You owe it to yourself to see these amazing videos filmed on planes that simulate zero G:

- JumpCrisscross 8y ago> They fly the plane downward, matching the vertical acceleration with the acceleration caused by gravity "Contrary to popular misconception, the 0 g freefall phase of flight begins as the aircraft climbs, and does not occur solely as the aircraft descends. Although the aircraft has upward velocity during the initial 0 g phase, its acceleration is downward: the upward velocity is decreasing" [1].

- hathawsh 8y agoGood clarification, thanks. By "downward", I meant downward acceleration, not necessarily downward velocity, although colloquial usage of "downward" usually means velocity.
