A U.S. Coast Guard aircrew aboard a MH-65 Dolphin helicopter hoists a fuel hose and nozzle assembly from the Coast Guard Cutter Bertholf (WMSL 750) to conduct a Helicopter in Flight Refueling (HIFR) operation while the cutter and crews patrol the Philippine Sea, April 12, 2019. Crews conduct HIFR training operations preparing them to transfer fuel while keeping the helicopter airborne in case the helicopter cannot land on the cutter due to bad sea state conditions, mechanical failures, an occupied flight deck or other reasons they cannot land.
