On board security, turn off Air Drop from strangers?
 

Bad enough some people are watching porn on flights but they want to share it too?

Thing is, IFE has content with nudity at least that wouldn't be appropriate for children nearby who might be able to see your screen.

Maybe the airlines should invest in those screen covers which block out the views of people not directly facing the screen?

Though in this case, it wouldn't help people who had porn Air Dropped on their big-screen iPhones and iPads.
