U.S. aircraft in Vietnam appear to have been extremely vulnerable to AAA

My understanding is that many repairable helicopters were destroyed at the crash site because of the difficulty in recovering aircraft when there were no clear "front lines".

Also, it would be interesting to find out how many were actually shot down, and how many were lost in bungled high temperature arrivals or departures at unprepared sites. That remains a leading cause of helicopter crashes today, even when nobody is shooting at you.

And a similar question for the fixed wing types: how many losses were really shot down, and how many were landing and takeoff accidents at relatively short and hot fields? RAF single engine fighter training losses roughly equalled combat losses for most of WW2.

Bill Walker,
Everywhere I looked there were slightly different numbers, but some good numbers would be 1737 losses to hostile fire and 514 operational for the USAF.
