Boeing Commercial Airplanes' Sonic Cruiser, tops the company's product-development agenda. Unveiled on March 29, 2001, the new concept features canards, a unique "gloved" delta wing, rear-mounted engines and two horizontal fins at the back of the airplane instead of the standard horizontal and vertical tail section found on today's jetliners. Recent analysis indicates the initial version of the new airplane will accommodate 200 to 250 passengers, fly between 6,000 and 9,000 nautical miles, and travel at a speed between Mach 0.95 and Mach 0.98 -- 15 to 20 percent faster than what currently is possible. It also will have a cruising altitude in the mid-40,000-foot level.
