If you have ever wondered what happened to your old aircraft, then here is a link https://www.helis.com/ that should tell you. It has information about every CH-46A ever made, as well as a drop-down list of all of the other CH-46 models and just about every other helicopter in the world.
For example, this link https://www.helis.com/database/cn/1229/ tells the story of the CH-46 hanging in the Naval Aviation Museum in Pensacola. She started life in 1965 when she was delivered to Boeing FR in Morton, PA, on 15 October. She was assigned bureau number 151952 and delivered to HMM-164 in December. She was transferred to HMM-265 in 1967. The site evidently permits visitors to post comments, because here is one posted by our own Gary Spevacek:
“I crewed this bird for most of ’68. I’m surprised we both made it back! I was with her when she suffered damage in July of ’68 when sand clogged the fuel filter on engine number 1 and we lost power lifting an external load of 105 rounds at Hill 55 and crashed into the ammo dump. She was lifted to MMAF where HAMS and a Boeing Vertol tech repaired her. She carried Raquel Welsh and Bob Hope in November of ’67 and was shot down a short time later. She was cannibalized and became mine in January of ’68. We both started flying around February 1st. Her yellow sheets should tell one heck of a story! She is an old friend and outstanding A/C. She was a Marine before joining the Navy. We were members of Marine Medium Helicopter Squadron 265. Semper Fi! – Gary Spevacek P.S. I was amazed to see 151952 hanging from the ceiling in the naval air museum . A long time ago her tail code was EP(Echo Papa) and her number was seven, she was painted green at the time.”
