In several instances during level-flight check tests of the operation of tail spin-recovery parachute equipment, the instability and the erratic behavior of the conventional flat parachutes used caused the airplanes to make uncontrollable gyrations. In order to determine whether a stable parachute could be safely towed behind an airplane in flight and also whether it would be effective as a spin-recovery device, the National Advisory Committee for Aeronautics has conducted an investigation with airplane models in the Langley free-flight and Langley 20-foot free- spinning tunnels. Both hemispherical and flat parachutes with a range.
