If you've ever tried looking out of an aircraft window at night when all the lights are on in the cabin you will probably notice that, unless you jam your face right up against the perspex and shield the gaps with your hand, all you can see is the reflection of your face and the groin of the person sitting in the seat next to you.
Now try to imagine all the cabin lights on and Miss Hosty leaning over you (oo er!) trying desperately to see which side the smoke is coming from before opening the door and telling you to jump and slide!!!
