well i must have remembered the plane wrong,but it had a rear ramp and spray equipment,but with y\'alls info it must have been a c-123...that is not the important thing as i\'m trying to prove that there was an aircraft at patrick henry at an airport display in the spring of 1971[maybe memorial day??]...it was on static display...by locating the aircraft ,then the maintaince records will show what i\'m in need of...if any pilot or crew remembers this event then it is a start in finding the tail numbers of the spray equiped planes there...thanks again...doc
