U.S. Air Force has restricted pilots weighing less than 136 pounds from flying the F-35A Lightning II stealth fighter following safety concerns about the ejection seat. Recent tests by the ejection seat maker Martin-Baker, has found the US16E ejection seat could cause an unacceptable risk of neck injury during parachute deployment/opening for lighter-weight pilots at low-speed conditions.
