Makes sense. There is a history of the Albatross being used here:
"In 1968 an agreement was reached with the DOD to utilize the Otis Air Force Base on Cape Cod as the new home of a Coast Guard Air Station. Coast Guard Air Station Cape Cod was actually established on August 29, 1970 when the Coast Guard Air Station at Salem, MA and the Coast Guard Air Detachment at Quonset Point, RI were consolidated, providing a much greater degree of efficiency in the maintenance and operations of the Sikorsky HH-52A Sea Guard and the Grumman HU-16E Albatross."
