Leonard, Thanks. I am in search of a map of Takhli showing the perimeter and cleared area's. As an A/C crew chief I did end of runway-last chance inspections, assisted in engine trim after engine changes and on several occasions assisted the bombers in getting the munitions from the bomb dump to the flight line. I can't remember the number of time the gun was replaced due to wrapped barrels and we had to sight it in. All area's that were cleared with AO and AB.
