(@SSD et al.) Agreed, airborne pictures of sky and scenery are a pleasure to watch.
But selfies? WTF?
(Besides, at least in my case, a selfie while flying would indeed be a risk to my "airworthiness". Not so much because of the immediate dangers of making one during flight, but I am so extremely handsome even when on the ground -- being exposed to the unearthly attractiveness of me while flying would probably blind me or drive me insane
