A federation of French and Japanese aerospace companies agreed in Paris last month to begin research on the development of a civilian supersonic transport airplane. The French group includes Airbus, EADS and Dassault Aviation, and the Japanese group comprises 98 companies, including Honda, Mitsubishi and Kawasaki. In Russia, Sukhoi has been working since the 1980s on SST technology, while keeping a low profile. Gulfstream is reportedly working with NASA to test a patented telescopic nose spike that would reduce the sonic boom of a supersonic business jet. The spike extends from 14 feet to 24 feet to reduce the shockwave intensity, Flight International reported last month. It has been installed on NASA's Boeing F-15 for flight tests.
