The apogee altitude was estimated by the nearby Edwards Air Force Base, based on radar data, to be 337,569 feet (102.9 km). Due to the early burn cutoff, this was far less than originally anticipated. However, it was more than the 100 km necessary to qualify as a spaceflight and satisfy X PRIZE requirements. Early reports said that after the instruction from the ground the pilot had delayed the burn cutoff in order to exceed 100 km; in fact the instruction was issued just after the 100 km altitude was assured, and the pilot's reaction time accounts for the additional 2.9 km.
