After boosting the trim power by 50 percent, adjusting the aerodynamics, and other modifications, two further mated test flights were carried out before Schoch was able to make a successful release and hookup on 14 October 1948. During the fifth free flight on 22 October 1948, Schoch again found it difficult to hook the Goblin to the bomber's trapeze, aborting four attempts before hitting the trapeze bar and breaking the hook on the XF-85's nose. Again, a forced landing was successfully carried out at Muroc.
