Canadair CL-52 Stratojet (Boeing B-47B), (Serial No. X059), on loan to the RCAF to test the Orenda jet engine.

In 1956, an American Boeing B-47 Stratojet was loaned to the Royal Canadian Air Force to flight test the Iroquois jet engine for use in the Avro CF-105 Arrow.  Canadair, the sub-contractor, attached an Iroquois to the right side of the bomber's rear fuselage, near the tail, simply because there was no other place to mount it.  Designated CL-52 by Canadair, it was a nightmare to fly, since the thrust was asymmetrical; this created great problems for flight control.  After the Arrow project was cancelled, the B-47B/CL-52, which had logged about 35 hours of engine flight tests, was returned to the U.S and subsequently scrapped.  The CL-52 was the only B-47 used by any foreign service.
