'Son of Concorde' is finally unveiled: NASA pulls back the curtain on its 100-foot, $247million supersonic jet that replaces the loud sonic boom with a softer 'thump' and can travel from London to New York in under 4 hours
Dubbed 'son of Concorde', the agency's new 100-foot-long plane called X-59 is capable of cruising at 937 miles per hour - faster than the speed of sound.
