There was a mad panic in N.Yorks one evening last Spring when a veritable squadron of UFOs flew over Roecliffe(Near Boroughbridge)Much telephonic traffic to RAF Dishforth,Leeming.Menwith Hiil etc.
Actually they were Chinese lanterns released from Newby Hall.Very effective they are too after a few bottles of Shiraz.Even the local paper got in on the act.
