We had arrived overhead some two hours earlier but were told to orbit whilst US Marine Chinooks airlifted marines onto the runway.
US Marine Chinooks? No such thing. The Marines flew the CH-46, the Chinook's little brother. It was officially called the Sea Knight, but the Marines called them Phrogs. The last USMC Phrog flight was in August 2015. The Phrog has been phased out in favor of the V-22 Osprey.
