Excuse me for resurrecting a three year old thread, but ...
I just stumbled on this documentary on Netflix:
https://en.wikipedia.org/wiki/Last_Days_in_Vietnam
An excellent documentary containing much information and video that I had never previously heard of or seen, including shots of the helicopters on the Gia Long building's elevator shaft.
Highly recommended if you are are interested in this piece of history and doubly so, if you have been to Saigon.
