In reply to AAZCD :
Was at Campbell the same time as you. I was 7-101 with the Chinooks. Was a TI on them. Retired in 96 and work in Huntsville, AL now.
Fortunate to say I've never been in a crash, came close more times than I can count. Closest was when I was a Huey crew chief as a PVT/PFC. Was at Bicycle lake at Camp Irwin crewing someone else's bird while mine was in maintenance, sent me back to Ord when mine was coming out of maintenance and got home late. When I went to work the next morning I found out the bird I was crewing had crashed into Bike Lake earlier that morning and the crew chief that replaced me was in the hospital with injuries. Messed up his back bad enough to get medically retired. Most concerned/scared was the dual engine failure on a Chinook while taking off from the north side of a mountain just off the DMZ of North Korea. No place to land, choices were side of mountain or no man's land which was the only sort of level spot. Fortunately the engines re-lit and we were able to fly away after dropping a couple thousand feet. Found out when we got back to base that the VIGV's went bonkers, closed and starved the engines. Lucky they didn't go through the engines as was what usually occurred when that happened. We got the newer engines without VIGV's after that and had no more problems.
VIGV = Variable Inlet Guide Vanes. Turbine engine usage. Not commonly used anymore because they would fail and go through the engine causing catastrophic failure, including coming out the side of the engine.
