A thermal coating extends from the root section of the airfoil toward the tip section of the airfoil.

A relative coating thickness of the thermal coating decreases by at least thirty percent at full span in the tip section, as compared to minimum span in the root section.

The aircraft's two fuel shutoff valves, one in each wing root, were found with one in the fully open position, and one in a partially open position.

The two General Electric J33-GE-5 turbojet engines were located in each wing root, which left the large and bulky fuselage free for fuel tanks and armament.

A favourable balance between induced drag reduction and increased wing root bending moment can thereby be achieved.
