I will think twice about flying on a 787.

As per Computer World:

“The internet of things, in a broad sense, is where we are starting to see everything from planes to cargo devices getting connected,” Bulman said. "The latest planes we are getting, the Boeing 787s, are incredibly connected. Literally every piece of that plane has an internet connection, from the engines, to the flaps, to the landing gear."

Seeing how online security vulnerabilities only proliferate, I can see some 12 year old deciding it would be cool to play flight simulator with a real plane.
