According to the Sunday Times a transatlantic flight is the equivalent of receiving a chest X-ray AND BA captains are rejecting flight plan levels and flying lower to the avoid cosmic radiation.
They have quoted a 747 skipper as saying "I stayed below 30000 ft all the way, the flight took half an hour longer but I didn't get my hair singed."
I find this hard to believe. Is this journo rubbish or what?
