Quite a localised thread, but this morning whilst on the school run in Salisbury there was a very loud, prolonged and very distinctly rough drone/buzz sound coming from the direction of Boscombe Down.
Was there a swarm of Helicopters flying round over there or is the Grizzly being further tested at the moment?
