Reduced gravity aircraft (parabolic flights) can reliably provide specific durations of near-zero gravity, typically lasting between 20 to 40 seconds per parabola.

The analysis

The claim states that Reduced Gravity Aircraft can provide a specific maximum duration of near-zero gravity. Retrieved papers such as [1] and [9] explicitly confirm that parabolic aircraft maneuvers provide consistent, measurable periods of microgravity (around 22 to 40 seconds per parabola). Therefore, the claim is supported by the literature.
