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?

Where there were electronics, there were tubes. Even in the
proximity fuses in artillery shells.

Was
that before transistors?

First transistors were invented in 1948.

Would the fighters and bombers be on
different frequencies?

Often.

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.

Cost, size, power requirements

Go not to the Net for answers, for it will tell you Yes and no. And
you are a bloody fool, only an ignorant cretin would even ask the
question, forty two, 47, the second door, and how many blonde lawyers
does it take to change a lightbulb.
