At what height do we fly?
Has anyone else sussed that a reply to this question could supply a "terrorist" with vital information to set a barometric device to explode a bomb, loaded in the hold of an aircraft on a given flight ,on a given day?
I know it's a bit over the top but it goes to show how an innocent question and reply could have serious repercusions.
Right, I feel better for writing that. It has bothered me all day.
