So I'm sitting on the train right now going into Paddington, and I have one of those 3 USB modem thingies that allow me to connect to the 'net over 3G. I have my headphones plugged into my laptop, as I'm attempting to search iTunes for a song I need. Suddenly, the song previews from iTunes are mixed with an odd static, which then clears up to a perfectly clear voice talking about the airspeed we're doing (at this point I've taken out the headphones to check whether the voice isn't originating from the train, but no - it's coming from my computer). After a couple of minutes of listening to some explanation of the way lift works, the voice then established this was an airship talking.
Very, very odd. I then disconnected the USB modem, and the voice went away.
