The resultant design aimed to carry 44 people across the Atlantic in around two hours, powered by twelve turbojets in two nacelles at what could be called the 'wingtips', although the Griffith was more of a blended-wing/lifting body design. For VTOL operation and perhaps low-speed forward flight, the entire nacelle could rotate through 90 degrees to direct the jet thrust downwards. This was augmented by 56 lift-jets, arranged in two double rows of 14 on either side of the passenger cabin, which could swivel for very low-speed control.
