Accused of the biggest military hack of all time", Gary McKinnon could be the most dangerous hacker in the world. Facing charges of hacking into 97 US military and Nasa computers and banned from using the internet in 2005, the 44-year-old will never touch a computer again if the US military has its way. Here, in his own words via email ... McKinnon gives [Independent on Sunday] readers an insight into how he feels after a four-year legal battle to stay out of the hands of the US authorities. [Q.] So, what punishment would be appropriate? [McKinnon:] A punishment proportionate to the crime and consistent with other accused hackers in the UK, including those accused of hacking into the Pentagon. 300 people a day still infiltrate Nasa and US military computers. There have been no other extradition requests from the US for any other hackers in the world. [Q.] What were you looking for at Nasa? [McKinnon:] Suppressed evidence of reverse engineered UFO technology, free energy that would help to stop climate change and would help to stop old age pensioners from dying of cold ... and also evidence of anti-gravity. [Q.] What did you find? [McKinnon:] A space fleet and an impressive UFO and a total lack of Nasa and military internet security.
