Black Bears - as in URS(bear) SCHWARZ(black)enbach.
Went to have a look at the Vampire today. The white building in the middle of the field looks a bit like a control tower and has the words 'Cresta Run' written on it. No clue why the Vampire is there but my son's classmate's dad works for the polo club and lives on the estate, so will ask!
Indicentally, there is an airstrip and small hangar just the other side of the A-road, visible in the GE image.
