"They can now be enjoyed "replaying historical recordings of flights in and out of London's Heathrow Airport""
I picture air traffic control enthusiasts and former air traffic controllers gathered around the machines, waxing lyrical about The Great Scare of 10 February 1982, or that day in March 1990 when the tracks of Heathrow's traffic briefly spelled the word WOPR. Like chess enthusiasts or indeed enthusiasts of any arcane art.
Alternatively, this is a great starting point for a disaster novel. Suppose the machine is accidentally plugged into the internet, and starts feeding historical flight recordings into its realtime equivalent? I'm sure it couldn't happen in real life, but then again this isn't real life, is it? And yet it's happening.
