A British man is appealing for the third time against his conviction over a joke posted on Twitter.
Paul Chambers tweeted he would blow up a local airport - closed because of bad weather - so he could fly to see his partner in Ireland.
Web users, including some celebrities, have supported the man saying his case is raising questions of internet freedom in the UK.
