  • Canada Aviation and Space Museum
    CANADA AVIATION AND SPACE MUSEUM BOEING MODEL 720B PRATT & WHITNEY CANADA FLYING EXPERIMENTAL TEST BED REGISTRATION C-FETB Introduction The practical era of jet-age passenger transport aircraft officially dawned when the British de Havilland Company D.H.106 Comet made its premiere flight to great acclaim from the Hatfield, Hertfordshire aerodrome in England on 27 July 1949. Catering to British and mid to long-range routes to European, Middle Eastern and overseas destinations, the Comet series of airliners carried their passengers aloft in luxurious opulence for more than twenty years. Military and test derivatives followed suit and these continued flying for many decades, including two Comets for the Royal Canadian Air Force (RCAF). Just 14 days later, across the vast Atlantic Ocean, in the small town of Malton, Ontario, Canada, a new aviation company called Avro Canada successfully accomplished the same task with much less fanfare and accolades. Avro sent its small, medium-range, turbo-jet transport, called the C-102 Jetliner, aloft for its first flight, inaugurating the dreamed potential for such a unique travel experience for the public on the North American continent. United States Air Force personnel found the aircraft favourable when they tried it out on flights at Wright Field, Ohio in March 1951. However, this Canadian dream didn’t last for long. The modestly successful Comet-series didn’t shine as brightly as its popular name when a series of tragic, fatal accidents to production civil aircraft nearly snuffed out its very existence. Following design rectification’s, the Royal Air Force continued to employ Comets in versatile roles, such as modifying the design into the Nimrod.

    USAFAlmanac ■ Gallery of USAF Weapons By Susan H.H. Young The B-1B’s conventional capability is being significantly enhanced by the ongoing Conventional Mission Upgrade Program (CMUP). This gives the B-1B greater lethality and survivability through the integration of precision and standoff weapons and a robust ECM suite. CMUP will include GPS receivers, a MIL-STD-1760 weapon interface, secure radios, and improved computers to support precision weapons, initially the JDAM, followed by the Joint Standoff Weapon (JSOW) and the Joint Air to Surface Standoff Missile (JASSM). The Defensive System Upgrade Program will improve aircrew situational awareness and jamming capability.
