A Hydrogen Bomb During Your Scheduled Flight

This article examines the physical consequences of a thermonuclear detonation from the perspective of passengers aboard a scheduled commercial flight at cruise altitude. Following the event from the first nanoseconds of energy release through thermal radiation, electromagnetic effects, atmospheric propagation, shock-wave arrival, aircraft structural response, and longer-term environmental consequences, the analysis connects nuclear physics with aerodynamics, human physiology, and aviation safety. Particular attention is given to the profound difference between what passengers would initially perceive and the physical processes already unfolding around them, including intense optical radiation, thermal exposure, blast propagation, and potentially catastrophic aircraft damage. By placing an ordinary airliner and its occupants within the evolving physical environment surrounding a nuclear detonation, the article translates otherwise abstract quantities of energy, temperature, pressure, and time into an aviation context while distinguishing scientifically supportable effects from popular depictions of nuclear explosions.
