If the balloon malfunctions, they can feel weightlessness until they reach terminal velocity. The problem is they're also going to experience a pretty large acceleration when reaching the surface.
- Someone 2y ago> If the balloon malfunctions, they can feel weightlessness until they reach terminal velocity Until they start decelerating, which is immediately. They’ll also feel it fairly rapidly, I think. https://en.wikipedia.org/wiki/Reduced-gravity_aircraft#Operating_principles https://en.wikipedia.org/wiki/Reduced-gravity_aircraft#Opera... (emphasis added): “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”
- meindnoch 2y agoTrue. Air resistance is always there, although negligible in the first few seconds.
- s1artibartfast 2y agoWeightlessness is very different than just equally balanced forces of drag and acceleration. If you crush something in a hydraulic press, it might have balanced forces and zero acceleration. For that matter, Im not accelerating when I lay on the surface of the earth, but I hardly feel weightless.
