Which personnel wear a white jersey on the flight deck?

The personnel who wear a white jersey on the flight deck are typically those involved in medical response and safety. The white jersey signifies that these individuals are part of the aircraft carrier's medical team, which includes corpsmen who are trained to render immediate aid to any injured personnel during flight operations. Their presence is crucial on the flight deck, as they are responsible for quickly assessing and treating injuries, ensuring the safety and health of the crew and other personnel working in the highly dynamic and potentially hazardous environment of the flight deck.

While other personnel in the options mentioned have specific roles—such as catapult personnel who help launch aircraft, explosive ordnance disposal teams that handle munitions, and tractor drivers who maneuver aircraft on the deck—they do not wear white jerseys. Each group has a distinct role that is indicated by the color of their jerseys, which helps to quickly identify their responsibilities in the chaotic flight deck environment.
