Scott,
You mentioned the vertical stab that Col Olds signed in Korea. Well here is one vertical stab he wished he had never seen. On March 21, 1967, two of his guys from the 433 TFS (64-0788 shown here) and (63-7586) were returning from a mission. They were trying to take photos of each other, got too close and had a mid-air. After we did the investigation, Col Olds had to go do another "Star Talk" (Brief the Generals) This was a real "Smoking Hole" when I came upon it in the jungle.

flyboy j,
You asked about Larry Rider. Sorry, but, I don't recall the name.
Warbird 1,
Reference the "Let Down" device:
The device was very simple. It consisted of a 100 ft roll of very thin nylon strap the pilots kept in a pocket on their lower left leg. If their parachute was caught in the tree canopy, they would take out the strap, feed it up across their chest, through their harness "D" ring and then on up over their head and tie the end around the parachute risers, above the riser buckles. Then they would hold onto the strap just below the "D" ring, reach up with their other hand and, one at a time, release the buckles on the risers. Then, they would repel down as the strap passed through the "D" ring. They controlled their rate of descent and speed of the strap going through the "D" ring by the angle in which they held the strap out in front of their chest.
We only had one failure. A "large" Lt Col was using it, the strap tore and he fell about 30 feet and broke a leg. Our investigation revealed he was repelling down very fast and stopped quickly about half way down to look around. The "D" ring was hot from the nylon strap passing through it so fast that when he stopped, the strap tore because it was weakened/slightly melted from the heat. We went to a heavier strap and retrained the pilots to come down slower and if they needed to stop during descent, to stop slowly.
