When I got back from VN I was stationed at Fort Wolters and we got our time in TH-55's. Used to fly down to Stephenville for chili at the airport then fly home. Thought we were in the high cotton when we got some old TH-13T's to fly then the OH-58's in about 1972.
As you remember, the TH-13T was the instrument trainer at Hanchey and Shell. I taught in it between tours. Never even one mechanical problem in over 1000 hours. I loved that bird. I went down to Vung Tau in 70 to get checked out in the 58. Always liked getting back into an H Model Huey. Those first OH-58s were very under powered.
