tKF - thanks chum, you youngsters are so good at technology!!

Ninjab - the pic is v dark (must have left the negative in the solution too long!) but top wing (and bottom) show Gene's influence.

Aerobatic aircraft generally have different schemes top and bottom so that judges can count the exact numbers of rolls!

If I can build an aeroplane - you lot can!!

I've had the loan of a 2 seat Pitts this w/e and have taken a couple of non-pilot friends up for a loop and a roll - none got as far as tKF (can we do an inverted spin?...) but I really think that everyone should have the opportunity of seeing the world from upside down. Makes all those silly meaningless things pale totally into insignificance!

What you doing next w/e, Ed?
