The NACA High-Speed Flight Research Station X-4 research aircraft is seen in this 1950s in-flight photograph. The X-4 Bantam, a single-place, low swept-wing, semi-tailless aircraft, was designed and built by Northrop Aircraft, Inc. It had no horizontal tail surfaces and its mission was to obtain in-flight data on the stability and control of semi-tailless aircraft at high subsonic speeds.1957NASA Photo / NACA/NASA› X-4 Project Description
