Heads up on snatch.

B-23 #39-28 was assigned to Wright Field and Clinton County Army Air Field the glider test and experiment base 35 miles from Wright Field. The photo in first post was made at Wright Field of the snatch of a CG-3A. I believe 39-28 was the only B-23 with a winch installed. December 1942 Col. Fred Dent flew the XCG-3 for a first time cargo glider snatch. Up until that time, only soaring gliders and a Piper Cub with prop removed had been snatched. The winch in the B-23 was a model 40 with a 4,000 lb capacity. Snatching the CG-4A required the model 80 winch and C-47 or larger tug. The first human snatch was done the first weekend of September 1943 at CCAAF.
Snatching a design weight (7,500 lb.) CG-4A, the glider would be airborne in less than 100 feet and it would be flying at the same speed as the tug (120 to 130 mph) in less than seven seconds. The G force on the glider was less than 7/10th of a G. This was done with a 225 foot long 15/16" diameter nylon tow line including the snatch loop which was stretched between two poles 12 feet tall. Normally approximately 650 feet of the 5/8" steel cable would pay out of the winch at which point the winch automatically would brake to a stop. All this in less time than a very short roller coaster ride. C-47 snatched CG-4A, CG-15A, CG-13A and British Horsa gliders.
In 1944 a B-17 was equipped with a model 180 winch. It could and did snatch CG-4A, CG-15A, CG-13A and the 26,000 lb gross weight CG-10A at net weight. One pilot who was involved in all the original glider snatch tests and the dead weight and human snatch tests eventually did over 2,500 snatches between 1943 and 1946. This system involved line stretched between two upright poles attached to the glider or human. This line was snatched with hook guided on a pole hinged down from the snatch plane. This required the snatch plane to fly at an altitude of approx. 20 to 25 feet for a short time at 120 to 130 mph minimum.
In all theaters during WWII there were over 500 CG-4A gliders snatched for recovery and reuse.
The Fulton system was devised around 1950 and involved a snatch line hauled several hundred feet vertically by a balloon and snatched by a plane with a huge V frame forward to protect propellers, etc. Check out the above site and the book, Silent Ones, as mentioned on the site.
