Aunty is reporting that the UK Civil Aviation Authority has come up with some firm evidence that mobile phones do in fact endanger aircraft if used while in flight.
‘In tests, compasses froze or overshot, navigation bearings were inaccurate and there was interference on radio channels. ‘
There’s also a story in a sidebar on the page which details how a plane had problems landing because some muppet passenger was using her phone at the time. Mmmm, not nice.
