Nutloose: Those pictures were taken at Tan Son Nhat and you'll find most of those airframes are still there, just off to the west of the apron for the domestic flights. There is even more interesting stuff inside the nearby hangers, but I know nothing of that...
I think you'll find your Chinook airframe has been patched up and moved to the War Crimes Museum in downtown Sai Gon; that was the plan anyway.
And, tsk tsk, the rest of you aren't
reading and understanding. Either that, or I'm writing poorly. I'm fully aware of where we've left 70's era airframes, I'm not fully aware of what YOU may have left or have seen. There are persistent rumours of ex-French-era airframes in near flying condition being around (in the South, obviously) when our American brothers left, but we don't know where and when, which is why I'm asking for your assistance.
