The Register, while always been an amusing---shall we say---IT-related media outlet, have been running an interesting competition lately.
In short, the task was to locate 'black helicopters' and other seemingly secret military hardware and isntallations using Google Earth.
Over the course of 11 pages, we're treated with loads of tasty and classified imagery raging from U2 spy planes in flight to military turbo props in North Korea. Also, do look out for the Russian space shuttle "Buran".
Who knew Google Earth could reaveal all this cool stuff!?
update: India is worried. heh.
