2.3 meter (7 ft 7 in) at the thickest point. The plan was to place passenger seating within the wings.
The prototype flew 6 or 7 times before crashing. Their were later claims of sabotage but the more likely cause was structural failure due to an unresolved issue with harmonic vibration in the tail booms.
