A hoax
The hoax about the BOEING 797 has been circulating on the web since 2006. Claims for a blended wing fuselage aircraft with the flying distance of 10,000 miles at Mach .88 have been refuted by the Seattle-based aircraft company, although some aviation experts have sourced the rumor to Boeing itself, since the company has been losing order to the AIRBUS 380. Easy for the corporate heads to foist a myth on the public than the real thing.
Another example of American free market capitalism at its best.
