There are so many electro-magnetic waves in the air, that if an airplane can't handle an iPhone it better not leaves the ground.
I'm sure your fellow passengers are happy that you are so cavalier about their safety.

Well, I asked the flight attendance for another seat to take photos. She probably didn't know about the phone-part, but was definetely aware of the electronic-part.
