I was on a plane to Copenhagen when it happened, terrifically happy that I had wifi and blogging away about this and that, when the IMs started coming in from friends in London. Passengers and crew came by to get updates as the flight terminated.

Thankfully my friends all seem to be ok, and are now taking very long walks home as the entire London transportation system has shut down.

There are lots of news sources on this, but here are a few to review as things develop:
