[ARC5] Basic Question on Use of Command Sets

[Bob Macklin]

The command sets were only used by the pilots and co-pilots. Bombers had a 
intercom set in a case the same size as a ARC-5/SCR-274 receiver.

All crew members were on the intercom. But the Command Set was not on the 
intercom.

Do you want to know the nosiest place in a bomber? It's the open waist gun 
ports! Especially in a B-25. You are looking right at the exhaust stacks!
