摘要

When a concorde jet on its way from paris to New York crashed on July 25, 2000 killing all 109 people aboard and four on the ground, the event was not simply a tragedy―it seemed a metaphor for the sorry state of supersonic air travel. Since its glamorous debut in 1976, the Concorde has remained a symbol of wealth and power but has become a technological dimosaur. It's still the only commercial airplane that travels faster than the speed of sound, but it burns so much fuel, and its complex 1960s-era technology needs so much maintenance, that fares are absurdly high:$12,750 roundtrip from New York to London. And then there's its biggest drawback: the Concorde's sonic boom―a thunderous double explosion that can shatter windows in the buildings below. This has restricted the Concorde to trips over water. Recently, though, supersonic flight has been making a comeback, Gulfstream, a company best known for making planes that chauffeur celebri ties and corporate execs across the skies, has been quietly hiring aviation specialists from NASA and Lockheed Martin. The company is especially interested in experts who understand the strange things that happen when air tries to flow around a supersonic airplane and who have experience with triangle-shaped delta wings and heat-resistant materials. People, in short, who may know how to silence the sonic boom. Gulf stream's goal: to make a passenger jet for the rich that can smash the sound barrier yet is quiet enough to fly anywhere, anytime. Imagine leaving New York at 7 a.m., flying to Moscow for a 2-hour meeting, and returning home in time for dinner. Or picture doing L. A. to New York in 2 hours, instead of the 51/2 it takes now.
