Great aircraft. I was a USMC Crew Chief on this aircraft and have flown on it many times. This aircrafts number was QF17175 with the US Marine Squadron H&MS-37 during the early & mid 1970'3 stationed at El Toro Marine Corps Air Station in California. We used the aircraft as a VIP hauler. I may still have some pictures of it back then. Great to see it still flying and would love to see her again. Mike from Illinois.
