Hy-BoLT
The Hypersonic Boundary Layer Transition (Hy-BoLT) experiment payload was sponsored by the Hypersonics Project within the Fundamental Aeronautics Program of NASA. Hy-BoLT was a wedge-shaped payload that would have provided "valuable data on the fundamental physics of high-Mach flight." It would have been launched to an altitude of 250 miles (400 km), transmitting various temperatures and pressures on different parts of the vehicle's surface.
During the flight, Hy-BoLT transmitted data as expected for the first 20 seconds until it was destroyed when the rocket was detonated.
