I was just wondering, we quite often see mistakes made by the mass media and by our friends and family, and other people we meet at airports or on flights. But what are the most frequent mistakes made by those who aren't knowledgeable when it comes to Aviation.
Obviously the first that comes to mind for me is mistaking aircraft for other aircraft, pointing out planes to children and naming them wrong, sometimes I guess its out of ignorance but its still pretty funny.
The one that I see most often is when i'm in an aircraft and as the aircraft is banking someone says 'wow look at the flaps move' when they are quite clearly ailerons (I mean honestly, how could someone make such a mistake

Calling the flight officer the captain is another one that happens alot.. I dunno, i'm pretty tired, what ones can you guys come up with?
