The X-24B “Flying Flatiron”: Paving the Way for Space Shuttle Landings

The X-24B, popularly known as the “flying flatiron,” was a wingless aircraft that played a crucial role in NASA’s piloted lifting body program. Its first glide flight took place on August 1, 1973, with skilled pilot John Manke at the controls.

The concept of a lifting body aircraft involves using the aerodynamic shape of the fuselage itself to generate lift, eliminating the need for traditional wings. This experimental design aimed to explore the feasibility of unpowered gliding landings for space shuttles, which could potentially enhance their reentry and landing capabilities.

The X-24B was not the first lifting body in NASA’s research. It was part of a series of experimental aircraft that began with the X-24A and evolved into the X-24C, with the X-24B being the intermediary model. The program aimed to gather essential data and insights into the aerodynamic characteristics of lifting bodies, as well as assess their handling qualities and landing performance.

Throughout the X-24B’s testing phase, it underwent a series of unpowered glide flights to study its flight behavior and handling characteristics. These glide missions represented a significant milestone in the program, as they provided valuable data for the development of space shuttle landing flight plans. Understanding how these unique aircraft glided and landed was crucial for designing safe and efficient space shuttle reentries and landings.

The X-24B was distinguished by its flat, wedge-like shape, resembling an upside-down iron or flatiron, which earned it the nickname “flying flatiron.” The aircraft’s design allowed it to achieve stable glides and demonstrated that lifting bodies could be viable options for controlled landings after atmospheric reentry.

Following the completion of the X-24B’s glide flights, the piloted lifting body program concluded. The knowledge gained from this program greatly contributed to the later design and operational aspects of the Space Shuttle program, which used lifting body principles during its reentry and landing phases.

In summary, the X-24B, or the “flying flatiron,” was an essential aircraft in NASA’s piloted lifting body program. Its series of glide flights provided critical data for space shuttle landing flight plans and marked the culmination of NASA’s endeavors to explore the aerodynamics of lifting bodies. The program’s success paved the way for the integration of lifting body concepts into the Space Shuttle program and further advanced the understanding of controlled landings for spacecraft reentering the Earth’s atmosphere.
