Smoking in Toilets
If someone has a cigarette in a toilet the detector may or may not go off, we are told. If the waste bin catches fire the detector will go off and crew will extinguish the fire with the appliances provided for that purpose. The first thing you might know about interference to aicraft systems caused by a mobile phone is when control is lost or you fly into a mountain or any other nasty event that might be caused by such devices. I'll settle for small fire of papers, if I have a choice!
