Coast Guard PB-1G (B17) ice patrol plane 026-g-051-005-001
Original caption: “Somewhere in the region of the Grand Banks of Newfoundland, taking a Loran fix in a Coast Guard PA-1G (B17) ice patrol plane, is John D. Murphy, Aviation Electronics man, 3rd class, working in close coordination with his navigator and the observer. By means of Loran, the navigator plots the plane’s position frequently over the fog-wrapped area under survey. Loran fixes enable the observer to check the exact location of icebergs along the course after they have been sighted. Working out from a Coast Guard attachment located at Argentia, Newfoundland, a four-engine PB-10’s ordinary search flight lasts 10 or 11 hours and covers approximately 1,500 linear miles. The 1954 International Ice Patrol season began in February and extended into August.” NARA 026-g-051-005-001
