THE RADIO OPS STATION ON A FEW AIRCRAFT


The aircraft listed in this document do not have any rhyme or reason. They are listed here because some data about their radio or electronics fit became available.
B-26 MARAUDER

This the radio operator's station in a B-26 Marauder bomber. This particular exhibit, as seen in the National Air and Space Museum in Washington DC, has been re-created in a fuselage section of an aircraft called "Flack Bait" (Photo by Jerry Proc)
Flak Bait served with the 449th Bombardment Squadron, 322nd Bombardment Group, Eighth and Ninth Air Forces. It flew from bases in England and, after D-Day (on which it flew two missions), from bases in France and Belgium. In 21 months, Flak Bait acquired more than 1,000 holes, had its hydraulic system shot out twice and its electrical system once, returned twice on one engine, and came back once with an engine on fire. By war's end, it had flown 202 bombing missions, more than any other American bomber over Europe. (Photo by Jerry Proc).

Wireless office of the German dirigible LZ126. From the book " Z.R. III - LZ 126 to America". The LZ126 was built in Friedrichshafen in 1924 for the U.S. Navy as part of reparations for WWI and was subsequently renamed the ZR-3 "Los Angeles". It was flown across the Atlantic from Germany to Lakehurst, New Jersey in October 1924.

LANCASTRIAN

The Lancastrian was a Lancaster bomber converted for civil use. It's main job was to carry  passengers trans-Atlantic and was the first Canadian aircraft to carry a flying radio officer. The a/c in the photo is  Lancastrian CF-CMW of Trans Canada Airlines as seen in  August, 1946. The major external  modifications were the extended nose section and the closing up of the bombay.  (Public Archives Canada PA-61649 via Spud Roscoe)
