A test
Further to 411A's non scientific but otherwise valid test. I've been in a Challenger with at least 3 phones in use. Miracle - we're still alive, I think!
I hav also received calls from the Flt Deck - before we got Satfone fitted
There's loads of anecdotal "evidence" but no hard facts
Simply boils down to cost. It's easier to ban than test - until now, when theres money to be made!
