Boscombe Down Aviation Collection, Salisbury (UK)
They don’t want to call it a museum. At the Old Sarum Airfield, you can not only marvel at the objects, but also touch them and sit in many of the cockpits. Many volunteers provide well-founded facts, which most of them have collected over their many years of flying or testing, repairing and manufacturing.
