Who are typically the people wearing blue jerseys?

In aviation operations, especially aboard aircraft carriers, personnel wear specific colored jerseys to easily identify their roles and functions on the flight deck. Individuals wearing blue jerseys are typically designated as aircraft handling and chock crewmen. Their primary responsibilities include directing the movement of aircraft on the flight deck and securing them in place with chocks. This role is crucial for ensuring safety and efficiency during flight operations, as they manage the aircraft's positioning and prepare it for launch and recovery.

The blue color of their jerseys helps other crew members quickly recognize their function amidst the fast-paced and often chaotic environment of the deck, enabling better coordination and preventing accidents. Those in other roles, such as crash response teams, medical staff, or plane captains, wear different colors, which are also designed to distinguish their specific tasks, but the blue jerseys are specifically associated with aircraft handling and the chock crew.
