I worked on those at NKP Thailand, USAF 1968-1969 , (wait--The base was never there and neither was I) don't tell anyone.
I did aircraft Sheetmetal repair (bullet holes etc.) Field Modifications and other things that cant be discussed here but included the remains to both aircraft and people. Nuf said
Anyway there were maybe 40 + A1e- A1J at times plus A26 15 to 25 , T28 at times (but they were not there either)
many Jolly Greens , Huey's + the Navy had the PV2 somebody else had Helio Couriers Dornier STOL But I cant discuss that either .
Look for a book called The Ravens, I think the authors name is Gregory or Douglas. There is a L19 that is on the cover, that book will tell you more than I can about on this forum that what went on from that base.
