Mark oversaw, among other programs, the A-10’s LASTE (Low Altitude Safety and Targeting Enhancements) program which includes commonly used technologies such as GPS navigation, collision avoidance, autopilot and multi-function displays. Mark’s work has contributed to the A-10 becoming one of the USAF’s most reliable aircraft, which continues to be one of the longest serving aircraft in aviation history.
