There have been a few as such and I always wondered if restraining the divers would help (typically they are loose in the cabin). Some type of quick release tether to hardpoints inside the cabin?
The one jump I made the airplane ride was way scarier than the jump. Hard to believe that thing was airworthy.
When someone would ask me why I’d jump from a perfectly good airplane, I’d tell them that they obviously have never seen a jump plane.
Ha! Though I never jumped there as I’d long given up skydiving before living in Chicagoland, I flew out to Rochelle a few times for lunch and I’d watch them jump. I even hopped a ride in the right seat of their Caravan when they took up a load one day. I also got a closeup look at their Twin Otter. Both aircraft appeared to be in pretty good shape so I really can’t criticize them at all. Two of the better jump aircraft that I’ve seen.
