This video made by PBS channel KPBS is about four men who flew aircraft in the VIetnam War.  One man was a helicopter gunship pilot.  Another was a Huey helicopter pilot.  The last two men were fighter pilots – a Navy A-4 pilot and a USAF F-100 pilot.  The intro to the video says:

The honest, personal accounts of four combat pilots during the Vietnam War. From helicopters to jets, these men reveal how they felt risking their lives in a war that was confusing and unpopular, to say the least. They share their missions, the close calls, and how they were treated when they came home. Saving lives by taking lives, changed them forever.”
