I worked on the GR5 (UK equivalent of the AV8B) at Dunsfold. About once a week one of our pilots would take one up to practice for a demo flight, and carry out these sort of manoeuvres around the airfield. When they did, all the buildings emptied and everyone lay on the grass and gawped. And at no time did I ever hear a manager suggest we get back to work, because this was what we were building. This incredible machine that was doing things no aircraft should ever be able to do.
