  • 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.

Using data collected from the U.S. Bureau of Transportation Statistics, we analyze 110 different aircraft types from 145 airlines operating U.S. commercial domestic service between 1991 and 2010. We classify the aircraft analyzed into four categories: turboprop, regional jet, narrow-body, and wide-body.

Church, Senior Editor ■ 2016 USAF Almanac BOMBER AIRCRAFT B-1 Lancer Brief: Long-range bomber capable of penetrating enemy defenses and de- livering the largest weapon load of any aircraft in the inventory. COMMENTARY The B-1A was initially proposed as replacement for the B-52, and four proto- types were developed and tested before program cancellation in 1977. The program was revived in 1981 as B-1B. The vastly upgraded aircraft added 74,000 lb of usable payload, improved radar, and reduced radar cross section, but cut maximum speed to Mach 1.2. The B-1B first saw combat in Iraq during Desert Fox in December 1998. Its three internal weapons bays accommodate a substantial payload of weapons, including a mix of different weapons in each bay. Lancer production totaled 100 aircraft. The bomber’s blended wing/ body configuration, variable-geometry design, and turbofan engines provide long range and loiter time. The B-1B has been upgraded with GPS, smart weapons, and mission systems. Offensive avionics include SAR for tracking, B-2A Spirit (SSgt. Jeremy M. Wilson) targeting, and engaging moving vehicles and terrain following. GPS-aided INS lets aircrews autonomously navigate without ground-based navigation aids Dimensions: Span 137 ft (spread forward) to 79 ft (swept aft), length 146 and precisely engage targets. Sniper pod was added in 2008. The ongoing ft, height 34 ft. integrated battle station modifications is the most comprehensive refresh in Weight: Max T-O 477,000 lb.
