I can understand that the headphones are styrofoam, because really, there is no one to talk to when you are in Airwolf. There is no one that can give you anything you don't already have, and anyone else in the air either can't catch you, can't find you, or will be shot down. You do not need to actually talk to them, because hearing "Checkmate, comrade" just before you blow up is not going to help you in any way.
I am mystified by the rest of this comic, but in a sense I lost all rights to anything making sense once the cartoon cat had a hit recording and threw parties catered by an alive stuffed bear and attended by *****s. This could all be a hallucination, or normal life could just return with no explanation, or Old Man McGreely could pull off the mask and be Spongebath.
Ultimately, though, we're missing the real point here, and that is this:
The theme from Airwolf was awesome.
