The picture with this caption puzzles me "A vortex made visible as powerback is used on a Boeing C-17 Globemaster III"

To me, this is just water being sucked from the ground - no matter which way the trust is being pointing. I've seen it on non-reverse planes too. 87.116.3.42 (talk) 08:04, 21 April 2022 (UTC)[reply]

It would be helpful to have a short explanation why "The amount of thrust and power generated are proportional to the speed of the aircraft, making reverse thrust more effective at high speeds" as it doesn't seem obvious. Intuitively I would have expected the relative speed between redirected airflow and airframe mass to be unaffected by airspeed. Searching the given reference (2) I can find no mention of this, only that reverse thrust is more effective at speed for a number of other reasons. 109.144.220.227 (talk) 15:33, 28 May 2023 (UTC)[reply]
