How does a zero gravity simulator used to train astronauts actually work?

They fly [this flight path](https://en.wikipedia.org/wiki/Reduced-gravity_aircraft#/media/File:Zero_gravity_flight_trajectory_C9-565_vector.svg).
Pull up, nose over, pull up on the back side so you don’t hit the ground.
Pushing the nose over in the middle of this maneuver *makes your momentum cancel out gravity.*
Gravity is still pulling on you. Hell, *it’s pulling on the moon 250,000 miles away.*
Weightlessness is NOT a lack of gravity. It’s CANCELING OUT the pull of gravity with your momentum. That’s the same thing in space. Orbiting the planet is just experiencing the middle part of that parabola for the entire path around the planet.
