Major Derald Smith's Photos
1966-67

"I took this photo from Chalk 2 in formation. This was an insertion near Dong Tre in late 1966." Note in bottom enlargement that the troops don't seem to be at a very high state of concern. Also note that this was before the Dolphins had the fixed doorgun mounts (not there), and this Dolphin has "174" painted on top of the right horizontal stabilizer.
