OV 10 Spotter taking off from Dau Tieng

These ov10 spotter aircraft flew almost straight down, and then launched 3.5 inch rockets filled with white phosphorus that targeted an area for a larger fast jet to bomb. We saw one of those in the battle of the crescent in may of 1969. The spotter fired rockets into an NVA basecamp, followed by a jet dropping 500 pounders.
