When a PPL flew himself into a misty hillside his fellow club members borrowed a coffin from the local undertaker to prove it would fit into a Partenavia. It did -- just about -- and as the deceased didn't mind a bit of a squeeze they flew him home.

My Paro needed overhaul of its wobbly prop at Scottish Aviation in Prestwick. To avoid its hefty landing fees I fitted my prop into a friend's MS880 which easily managed a short grass strip some 20 miles south.
