A man who became separated from his family for 25 years has tracked down his birth mother using Google Earth.
Saroo Brierley was five when he went to help his nine-year old brother who worked on trains in Khandwa, India. He fell asleep on the train journey there and woke up hundreds of miles away in Calcutta.
Mr Brierly was able to find his Indian mother by scouring Google Earth for four years and using the memories he still had of the town in which he used to live.
Devotion, love, smarts. A good geek story.
