A Doncaster man who was found guilty of posting a message on Twitter threatening to blow an airport "sky high" is to appeal against the verdict.
Paul Chambers, 26, claimed he sent the Tweet in a moment of frustration after Robin Hood Airport in South Yorkshire was closed by snow in January.
The trainee accountant, who lost his job because of the prosecution, said his family had "been through hell".
He has sought legal advice and will appeal against the verdict.
Chambers was found guilty at Doncaster Magistrates' Court last Monday of sending a menacing electronic communication.
He was fined £385 by a district judge and told to pay £600 court costs.
'Stunned' by arrest
The Tweet he sent to his 600 "followers" in the early hours of 6 January said: "Robin Hood Airport is closed. You've got a week... otherwise I'm blowing the airport sky high!"
He said: "In the cold light of day it sounds bad but within the context it was as much of a threat to the airport as fast food is to fine dining."
Chambers said he was "stunned" when he was arrested by four police officers at his work a week after he posted the message.
A Twitter fund has been set up to help him fight the case. Chambers said Stephen Fry, who has more than 1.5m Twitter followers, had also offered to pay his fine.
He said: "I have had some criticism, some people say I got what I deserved but people have generally been supportive."
