Wow. Someone at ABC News Online has the awareness and the skill set to integrate coverage of the London transit attacks with GoogleEarth.
HIGHLY recommended. This is really quite amazing.
Could this become a mainstream means of reporting?
UPDATE: Instructions for the *.kml format that enables users to merge content of their choice with GoogleEarth; and GoogleEarthHacks, a user community where you can find additional content. My favorite is Flickr Images, which finds the 50 nearest to your viewing location.
