Crew Bus and Post Flight Beer

Takhli, Thailand, 1973. I took this photo from rear on one of the familiar dark blue and noisy USAF crew buses that took us to/from the C-130 when we flew. Here Joe (navigator) on left stands next to Tony (flight engineer) giving the one-finger salute. Captain Ed (AC) watches from front of bus. Notice we all already had beers in hand as it appears late after returning from the day's sorties that were probably into Vietnam as was the norm. Signs in bus only said No Smoking so I guess Drinking was OK at least upon return from flying :-).
