I thought the first twenty minutes or so of Pushing Tin was a pretty entertaining caricature of the job and (some) of the people who do it. ATC was pretty incidental after that.
Blackout Effect stretched the bounds of credability pretty far but it did make me think, what if everything did go? Having just moved to Swanwick it wasn't a totally idle thought. Making a sprint for the nearest telephone outside the system armed with a number for TC didn't seem so unreasonable on reflection.
