CAPT Charlie Plumb, USN (ret) was an A-4 pilot during the Vietnam War.  He was shot down by a surface to air missile and spent six years in the “Hanoi Hilton.”  After returning home he he continued his service in the Navy until he retired and he still flies and he wrote the “Forward” for “STUGGLE WELL” by Ken Falke & Josh Goldberg.  This is a TEDx talk he gave at a high school, it is worth your time.
