26-year-old Chambers will go on trial today after allegedly posting a Tweet that threatened to blow an airport 'sky high'.
Chambers, of Balby, Doncaster, denied tweeting the message about Robin Hood Airport in Doncaster on January 6.
The post was picked up by routine investigations into the site, which lead to Chambers' eventual arrest.
The alleged tweet read: 'Robin Hood Airport is closed. You've got a week... otherwise I'm blowing the airport sky high!'
Twitter users have mounted a campaign to raise awareness of the trial, with #twitterjoketrial appearing high in the UK trending topics.
Update: He has been found guilty and fined £1000.
