"The U.S. Air Force followed these developments [The recent developements in high speed aircraft design include things such as fuels, aerodynamic shapes, etc...] closely, and in 1955 issued General Operational Requirement No. 38 for a new bomber with the payload and intercontinental range of the B-52 and the Mach 2 top speed of the Convair B-58 Hustler. The new bomber was expected to enter service in 1963. Both nuclear and conventional designs would be considered. The nuclear-powered bomber was placed under "Weapon System 125A" and pursued simultaneously with the jet-powered version, "Weapon System 110A". - Wikipedia

Enter North American Aviation's answer to the Air Force's contract: the NAA WS-110A. This unusual concept plane never lefted the drawing board, but was instrumental in the evolution of its future self, the North American XB-70 Valkyrie. The WS-110A featured huge wing tip fuel tanks that could be jettisoned when their fuel was expended before a supersonic dash to the target. The tanks also consisted of the outer portions of the wing, which would also be jettisoned to produce a smaller wing whose shape was better suited for supersonic speeds. Both became trapezoidal wings after ejection; at that time the highest performance wing design known by aerospace engineers. They also featured flush cockpits to maintain the highest fineness ratio possible even though it had a negative effect on visibility of the pilot/co-pilot. This plane is a bit laggy on older or weaker mobile device so for those I would recommended a lower graphics setting. iPads and high-end Android devices should have no forseeable issues. As always, good luck and safe flying.

The wings on this plane are jettisonable by using Activation 1.
