I used to be an instructor close to a military base with a bunch of HALO qualified dudes stationed here. They used to come to the DZ to get transition training for civilian gear. I can’t tell you how many videos of these guys I saw that literally scared me. It was way too common for them to pull their BOC pilot chute and hold on to it as if it were the rip cord on the HALO gear. Many times they would hold on until decision altitude, let go of it to grab the cutaway handle and end up chopping a canopy that was actually reaching line stretch. One of the most memorable of these videos had the AFF instructor on the jump slapping the shit out of HALO boy’s hand to try to get him to let go of the pilot chute.
