Was working on my MT Mustang last night, setting up the Aileron bell cranks so had the wing in right side up in the saddle, plane upside down in a Workmate bench. Well after some time came to the conclusion that a trip to the LHS was in order.

Went to refresh my drink, came back, and decided to work on the air scope. This required the wing bolts to be screwed in and the wing snugged up for a tighter scope to fuse fit. The bolts were totally off, I couldn't understand it, measured, moved the wing around, took it out of the saddle checked for warp....are you getting the picture.

Still standing over it, decided it needed to be re-drilled. In disgust I sat down at my chair shaking my head, wondering how the hell this could have happened. Looked over at the plane and noticed the wing was in right side up. Duh!
