Speed tape, the goal is to reduce drag for small things like paint chips and such. During takeoff/landing, the most dangerous thing is stalling due to low speed, so a little bit extra drag can be a big deal. Looks like there’s so many wrinkles in most of that tape that it probably is being counterproductive.
The best scene was where one character was in handcuffs and kept rolling too low to get out and the camera kept switching from one character who was doing awesome stunts back to them doing nothing useful the whole fight.
