Google Space Launches at London’s Heathrow Airport to Fill Passengers’ Dead Time

Google Space is a laboratory comprising Google pods, which travellers can access for free once through security to log onto the Internet, check their mail and use Google tools to find out about their destination.

A big part of this set-up involves Google Earth. It should be quite a crowd attractor with people, I suspect. Here is Google Space’s home page.
