Call me naieve, I havn't been around long, but is loss of communication a more serious problem to an F18 than it is to any other aircraft?
I know they are old aircraft, but surely they have other ways of avoiding colision. At the very least the airliner has TCAS and, if all else fails, shock horror, the crew of the airliner and guidance of good old ATC???????????
Loss of Comms......No problem to most well experienced operators............
