JetZero, a start-up company based in Long Beach, California, is developing a blended-wing-body (BWB) aircraft for the so-called “middle of the market” (MOM) segment occupied by the remaining Boeing 767-300ER and 757 models, older and current-generation Airbus A321s, and the forthcoming Boeing 737-10. Older Airbus A330 variants and current-generation aircraft such as the Boeing 787, Airbus A330neo, and A350-900 also serve this segment.

The design is a 250-passenger airliner, the same size as the larger “new midsize airplane” (NMA) concepts that Boeing explored but did not bring to fruition. JetZero says the BWB will be 30% more aerodynamically efficient than the aircraft it replaces. The company compares the economics of its Z4 aircraft with the Boeing 767-200ER. It has not compared the Z4 with the current-generation aircraft that the BWB would actually compete against for sales and costs.
