Documents / FOIA release
This Central Intelligence Agency release, declassified and approved for release on 24 June 2013, is a collection of UFO photographs and pages from flying saucer books. It reproduces pictures including the Coniston saucer, the Trent photograph at McMinnville and a radar plot from Washington, D.C. Airport of 15 August 1952. The pages also discuss the Norwich sighting by F. W. Potter, the Bicknell sighting near Kilimanjaro, Maury Island and Farmington. The CIA adds no analysis of its own.

Plate 1 Author's impression of the A.V. Roe Project exhaust ports. Air is drawn in the leading edge intakes and a large proportion of it is fed to the combustion system in the usual way; the remainder by-passes the engine and mixes with the exhaust, which leaves via guide or central vanes in the exhaust ports. It is said that the aircraft will be capable of speeds up to 1,500 miles per hour, while it is also claimed that 180 degree turns will be possible 'without a change of attitude', though what is meant by the latter is not at all clear. Neither is it clear how the rotating power plant will give gyroscopic stability in normal flight, yet fail to pull the aircraft to pieces through gyroscopic couples in high speed aerobatic manoeuvres. In fact it is the ability of the real flying sauce to execute such acute manoeuvres while rotating about its axis, that helps to put it outside the school of aerodynamics and, for that matter, Newtonian mechanics. It is extremely likely that we are not the only nation interested in the flying disc design. Russia is no doubt doing her share in the mad race to get there first. Saucers recently skimmed the rooftops in Belgrade and it was suggested that they were experimental models made by the Yugoslav Air Force. These miniature saucers are said to be forty inches in diameter, to weigh about four pounds, with a top speed of thirty-one miles per hour and to be radio controlled. Doctor W. F. Hilton, Armstrong Whitworth's chief aerodynamist, when giving a lecture to the British Interplanetary Society at Birmingham (1952-3 session), on the difficulties of bringing a returning space ship down to earth, said: 'That a space ship returning from an interplanetary flight would enter the earth's upper atmosphere at a speed equivalent to a Mach No. of 35 and would be burned up in a few minutes in those conditions'. One method to overcome this is for the craft to approach the earth at an angle, thereby skimming the upper atmosphere. In such a contact it would pick up all the heat it could withstand and then fly off into outer
