I have interviewed eyewitnesses about large triangle craft for years. In my book Glimpses of Other Realities, Volume II: High Strangeness (Earthfiles Shop), I reprinted pages from a government document entitled Extraterrestrial Entities and Technology, Recovery and Disposal" classified TOP SECRET/MAJIC EYES ONLY and dated April 1954 by the U. S. War Department.
In a section about different kinds of extraterrestrial craft, the U. S. government manual states: "Airfoil or triangular shape. This craft is believed to be new technology due to the rarity and recency of the observations. Radar indicates an isosceles triangle profile, the longest side being nearly 300 feet in length. Little is known about the performance of these craft due to the rarity of good sightings, but they are believed capable of high speeds and abrupt maneuvers similar to or exceeding the performance attributed to disc or circular (shaped craft)."
