A major objective of Phase II-A has been to achieve a supersonic transport economically competitive with subsonic airplanes. The Model 733-290, with a direct operating cost of 0.9 cents per seat statute mile, accomplishes this for intercontinental operation. The Model 733-291, identical in all respects except for gross weight and operational empty weight, provides an equally economic airplane for domestic operation. The community noise associated with both airplanes is significantly less than for present subsonic jets. Many configurations have been considered in Phase II-A. The most promising, Model 733-290, is a logical development of the variable-sweep airplane proposed in Phase I. Substantially improved supersonic cruise efficiency has been achieved with no compromise in the outstanding low-speed performance and safety characteristics. (Author)
