Sorry, Ta - I haven't the faintest idea ! [img]redface.gif[/img] I've stored it at the back of my mind for further investigation.
Another fascinating one is REIMAHG in Thuringia. Previously in East Germany, this is now being researched and opened to visitors by a local group. It was an enormous facility for producing the Me 262. The top of the mountain was levelled and completed aircraft were to be winched up from the factory complex and flown off with rocket assistance. In the event, only seven aircraft were completed here before the war ended.
Sounds like a Bond movie, but it's true !
