They have never admitted to a UFO sighting in how many years the unit has been active? A lot of "unexplained" for sure, so hardly surprising it is closing.
There was one exception I believe. An MOD missle/shall went astray years ago and nearly clobbered an aircraft. The crew filed an airmiss report, right down to the size,shape and colour of the thing. Some bright spark at the MOD suggested they get off the hook by confirming it was a UFO!
