Hatches are openings or doors in a structure, often used for access or ventilation. They can be found in various settings, such as ships, aircraft, and buildings. Hatches are designed to be secure and may include mechanisms like latches or locks to ensure safety. In maritime contexts, hatches are crucial for loading and unloading cargo. They help maintain the vessel's integrity by allowing for controlled access to different compartments. In aviation, hatches can provide access to equipment or emergency exits, contributing to the overall functionality and safety of the aircraft.
