The Sonic Cruiser was a Boeing concept from 2001, it could cruise up to Mach .98. The idea was that it would fly just below the speed of sound, but be muh faster than any other airliner, without the downsides of supersonic flight (i.e. no sonic booms). Boeing cancelled the Sonic Cruiser in 2002, in favor of the 7E7, which would later become the 787 Dreamliner.
