The engines compensate for the air resistance
That's not how zero gravity is achieved. It's done by parabolic dives that result in periods of simulated zero gravity.
- eesmith 7y agoFrom the Wikipedia page I pointed to at https://en.wikipedia.org/wiki/Reduced-gravity_aircraft https://en.wikipedia.org/wiki/Reduced-gravity_aircraft : > The sensation of weightlessness is achieved by reducing thrust and lowering the nose to maintain a neutral, or "zero lift", configuration such that the aircraft follows a ballistic trajectory, with engine thrust exactly compensating for drag. "air resistance" (my term) = "drag" (WP) "The engines" (my term) = "engine thrust" (WP) It seems that I am substantially correct, yes? Or are you picking at the specific wording I used?
