Also, many places people think are air gapped aren't any more. Think smart lightbulbs and bluetooth worms. A hacked android device that gets too close to the perimeter can infect the lightbulb which infects the next one on and down the chain. If someone networks the control computer for the lights to the same network with the classified files it's lights out.
I think of the internet less of a binary thing these days and more of a spectrum. Things can be "pretty dark" like in the basement of NORAD or "white hot" like the twitter feed of Donald Trump. But twitter still goes down sometimes and data can be exfiltrated in so many ways. What's the baud on opening and closing vents and reading it from space satellites?

Here's an example where researchers used a scanner in an office building to exfiltrate data from the network. Malware on the network activates the scanner in a certain pattern, which lights up the room. The difference in lighting is recorded using a drone outside across the parking lot:
