I tried this on the freedom with 10 blackwasps and spread them around randomly. I then entered all of them and made sure they were not stuck by pulling forwards. In the 2 tests only 1 had their rear wheels stuck. This also did not happen when I got into the aircraft, rather it seemed to drop when when I entered other aircraft or when it spawned, When I ran same scenario again the plane was fine.

I tested this on the dev branch and got some weird results. First off, I dont have any friends so I couldn't use another player to laz for me but I did try using the sub which is the only vehicle I know of with a laser besides a plane. So here are my results: If I jump in gunner seat and start lasing while no one else was in the vehicle, and then ejected and went back to a plane, the laser would not show up. However if I did the same thing but had someone in the driver seat of the sub, then the laser would stay on, and it would stay on the exact right position, I did 2 bombing run tests on the same target same path with same sub and I got all hits on the first and one miss on the second (this might be because I had already gone past target with laser on it by the time the bomb hit, which could cause it to miss. Further testing will be needed. (I restarted scenario between each test)

There is a control option in key bindings planes for the air brake (should be at bottom of plane control list) I bound mine to H

weird it seems to only happen when you are like 1 ft off the ground.
