In the late 1968 or 69 I took a normaly asperated Piper Apache up to 20,300 . Tho owner of the plane had just installed a large camera in the back seat area and was using it for aerial surveys and wanted to see how high it would go.We had oxygen and were up there for about an hour with the mixtures just about back to the shutoff and making very gentle turns for fear of stalling. That day was the first picture with the airlpane and camera over Valdosta GA. at 20300. This same plane made the aerial surveys of Disney World before they started construction of Disney World.
