I was tasked to shoot BW photos in freefall of each jump for documentation. Chip Maury shot movies. They brought in a Special Forces top gun to do the jumps, but he could not get stable. When they were ready to scrap the project we suggested a SEAL give it a try. He did and the test proved feasable. Guess what would go in the 70# container? Read an old copy of Soldier of Fortune and you will discover that it gives the army credit.
