Unveiled on March 29, 2001, the new Sonic Cruiser concept featured 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. The aircraft was planned to 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 would have had a cruising altitude in the mid-40,000-foot level.
