The UK government has released many UFO related files that had been classified until just recently. The attachment contains two sets of letters, the first few involve an inquiry into a UFO matter made in the 1990s. The Royal Air Force quoted the original documents, including claims that an aircraft had matched the speed of an airplane in a way that no craft of that era could. The second set of letters gives more detail into the occurance, an RAF airplane taking pictures was returning to England when an unidentified craft came near to it and began matching its speed. The pilots took pictures before it cruised away without making a sound. This incident was a point of intense discussion between Churchill and Eisenhower before Churchill decided to put the thing under lock and key for fifty years.
