I've recently seen a movie, entitled Red Tails. About the Negro
air men who fought over Italy.

What makes me wonder. The fighters and the bombers did
not appear to be able to talk with each other on the two way
radios. I'm curious what kind of radios they had. Tube sets? Was
that before transistors? Would the fighters and bombers be on
different frequencies?

The transistor was not developed until the 1950s. Patents on solid
state replacements for triodes were filed as early as the 1920s, but no
working prototype emerged for another three decades.



Now days, I think most air planes have two radios, and one is
always set to the emergency freq. But, then, the cost of radios has
come down a bit.
