KENNETH ARNOLD'S UFO WAS A CANBERRA BOMBER

"Arnold estimated their size at about two-thirds that of a DC-4, and he calculated their speed at over 1500 mph by timing their travel between two mountain peaks of known distance." The length of the fuselage of the Canberra is 66 feet long. The length of a Douglass DC-4 is 94 feet long. This equals the two-thirds estimate of Arnold's. The Canberra test flight program began in at least 1947 and the plane was flying at speeds above MACH-2. Washington State, where Arnold had his sighting, was also home to America's nascent nuclear program. Hanford Washington was a major part of the Manhattan Project. The facilities there would have the ability to service the nuclear aircraft. 

TIMELINE

09 January 1946

English Electric received a contract to produce four prototypes, which received the Society of British Aerospace Companies (SBAC) designation A.1; work commenced on the construction of these prototype aircraft in that same year, which were all built on production jigs.

The first UFO reports for Project SIGN

July 1947

Pentagon officials were expressing alarm about the flying disk reports

October 1947

In response to Rolls-Royce's difficulties, English Electric elected to have the second prototype modified to use the existing Nene engine in place of the Avon.[6] The implementation of post-war military cutbacks also served to slow development.

20 September 1948

Ramjets being tested in Los Angeles breaking the sound barrier.

February 1949

First Canberra Flight

28 September 1949

“45,000 horsepower is required to drive a 25 ton plane 1500 miles an hour (MACH 2.27) at 70,000 feet. … The power requirement would jump to 200,000 horsepower at sea level because of greater air resistance.”
