Just tidying up the garage, and heard something "odd", so went out o look, and there overhead (East Yorkshire) were two V22 Ospreys, the tilt rotor thingies, looked mighty weird, and a unique sound.
Something sounding very unusual woke me up just before 4pm this morning, flying very low over my house. Sounded like a cross between a heavy helicopter and a freight train with a bit of jet whine. Wonder if that was an Osprey?
