Multiple reports describe a Royal Air Force Chinook helicopter carrying out a maritime training exercise with Royal Marines. Footage shows the aircraft flying very low over the sea at dusk, with the landing gear appearing close to the water as crew members lower Royal Marines into the ocean from the helicopter. The Marines are placed into a rigid inflatable boat (RIB), which operates alongside the aircraft during the drill. The training is presented as an example of pilot technique and aircraft handling during ship-to-shore or waterborne insertion scenarios, where helicopters must approach low over water and precisely deploy personnel and equipment while maintaining safety margins. Across the accounts, the key elements remain consistent: a Chinook helicopter, Royal Marines taking part, a low-hover maneuver above open water, and the transfer of Marines into a RIB during the exercise. The reporting does not provide additional operational details such as location, date, or specific training objectives beyond the general maritime insertion and deployment context.
