Bill Burnett, IIRC, made at least wg cdr. Hugh Davis was very much in to the bare knuckle stuff - combat survival - some years before your print he was involved in rear crew drogue gun operated parachutes.
He was at Akrotiri throwing dummies out of a Shacklebomber flying at about 300 kts. I believe the drogue guns worked perfectly but in the end the idea was abandoned as it would have led to the rear crew moving aroung the cabin with a live drogue gun.
