Sorry we missed you on Friday. We hope this cracker of a podcast makes up for it. Today, we devote the entire podcast to the strange tale of Gary MacKinnon, a British hairdresser turned computer hacker who is wanted by US federal prosecutors. MacKinnon is accused of committing "the biggest military hack ever." MacKinnon says he wasn't being malicious; he just wanted to find out if the US government was withholding information about UFOs. We examine the case, in full, today on The World's technology podcast.
