I feel the need to exercise considerable caution in this. These pages are read by many journalists and we are in difficult enough times without hysterical fear-mongering by fellow pilots. If we are openly saying that aircraft are even now about to be taken over in their hordes by 'sleepers, who will then carry out even more deranged acts than we have already seen then we are just adding to the frenzy. This is a time for calculated action, wisdom and common sense and it is certainly not a time to be feeding on people's worst fears. Do we want an airline industry or not?
