[Milsurplus] How could radio ops hear anything in B 17, B 24 etc?

[BOEING377@aol.com]

A couple of years ago I was at the World free Fall Convention in Quincy 
Illinois. I was fortunate enough to be able to make a freefall jump from the 
Collings Foundation's beautifully restored B 24 bomber. We went out right through 
the bomb bay. I had hoped to be able to fool around with the BC 348 rcvr during 
our climb to jump altitude, but it was not to be. The good old BA gear was all 
there (BC 375, BC 348 , etc.) but not even hooked up. The noise level inside 
the plane was very high.  I have used WW 2 headphones before and know that 
they do not do a very good job of blocking external acoustic noise.  I also know 
that the audio output levels from the receivers and interphone amps were not 
exactly ear slitting either.  How did they do it?  I doubt if I could have 
copied much under those conditions.
