And all because they cannot add, it would appear
Well, it would appear neither could young Stricklin in his F16!
When Stricklin realized something was wrong, he exerted maximum back stick pressure and rolled slightly left to ensure the aircraft would impact away from the crowd should he have to eject, the Air Force said. He ejected when the aircraft was 140 feet above the ground. There was no other damage to military or civilian property. Also, the board determined other factors substantially contributed to creating the opportunity for the error to occur, including the requirement for demonstration pilots to convert AGL elevations to MSL altitudes, and performing a manoeuvre with a limited margin of error. Instead of just zeroing the altimeter to deck level as a result of the crash, procedures have been changed to require that Thunderbird pilots climb an extra 1,000 feet before starting the Split-S manoeuvre.
