Which door do the #1-4 jumpers load into the UH-60A?

The #1-4 jumpers load into the starboard door of the UH-60A primarily because of the aircraft's design and operational procedures. The starboard side door offers a more efficient exit point for the jumpers, as it allows them to jump out while maintaining clear space for both the aircraft's operations and the surrounding environment.

Additionally, the choice of the starboard door is based on safety and tactical considerations. Loading from the starboard side can help mitigate potential hazards from the rotor wash and ground wind patterns, ensuring that jumpers have an unobstructed path to exit the aircraft quickly and safely.

Understanding the specific loading procedures for each type of aircraft is crucial in jump operations, as it ensures that all members can perform their jumps efficiently and in alignment with established protocols.
