Unfortunately both Ian Ladley and Dougie King (aka Skull on a Stick) have passed on to that big gliding field in the sky. Ian flew Tiffies during the war. Dougie had a succession of London taxis for his personal transport. Both were great characters.
High Tow.
I can confirm that a motorcycle, in this case a Norton 850 Commando, will go up the side of a Lamella hangar with ease.
Coming down the other side, however, is a different matter!
