Essayist: Some researchers criticize British governmental security agencies for not releasing enough information about sightings of unidentified flying objects (UFOs) made by these military and intelligence agencies  Requests for information by civilian researchers are brushed aside
This leads one to suspect that there have been spacecraft sighted near Earth that are extraterrestrial in origin
The British government would withhold information pertaining to UFOs only if it were established that they were from other planets.
