Description
Jiongxiang Zhao and co-authors use computer models to ask how fast a pilot's neck muscles must react during an ejection, in a 2026 study. Ejection throws the body upward at high force, and the neck takes a hard load in a split second. Muscle timing could decide whether the spine bends too far and gets hurt.
Their model of the neck and upper back ran trials with reaction times from very fast to slow. Early action kept the spine steadier, while late action let lower neck joints bend too far. A mid-range timing gave the best balance. The results can shape training and gear that guard pilots in that brief, violent moment.
