A drunk British plane passenger who threatened to "do a 9/11" and kill everyone on board has been jailed for eight months.
Jason Clarke, 47, was loud and "abusive" throughout the flight, swearing at terrified passengers and crew members who applauded when he was arrested on landing.

He behaved "appallingly" for the two-and-a-half hour journey, crawling around on the floor and even threatened to urinate on his seat.
Clarke had necked six pints before boarding the Birmingham-bound Ryanair flight from Malaga, Spain at 7.35pm on January 13.
But when he sobered up the next day he told police alcohol "affects his personality" and he said he could not remember his behaviour and apologised.
Clarke, of Castle Vale, Birmingham, admitted entering an aircraft while drunk and was jailed for eight months at Birmingham Crown Court today.
Prosecutor Peter Grice said: "During the flight the defendant was loud and abusive towards both passengers and crew members.
"It began with him singing loudly while listening to music on his headphones.
"After he was asked on at least six occasions to quiet down he swore at passengers.
"He made comments about doing a 9/11 and taking the plane down. He threatened to kill them all.
"Towards the end of the flight when the seatbelt signs were displayed he was prevented from using the toilets.
"He threatened to urinate on his own seat."
He added that Clarke was arrested following landing and taken to Solihull police station.
Recorder Anthony Warner said: "By the time you got on that flight you were obviously very seriously affected by drink.
"The other passengers were subjected to continuous abuse by you towards them.
"When your behaviour was drawn to your attention you continued to be drunk and abusive.
"Staff attempted to intervene to moderate your behaviour, which it is their duty to do, but you didn't do that.
"You were arrested by the police as soon as the flight landed and unsurprisingly the other passengers greeted that with some relief. "
He said that the passengers couldn't get away from Clarke because they were trapped in the same aircraft, giving them a feeling of powerlessness.
Anthony Warner also said that Clarke's behaviour persisted even when staff tried to intervene and that what he did was "appalling".
The court heard he was suffering from "anxiety and depression" following the breakdown of a relationship.
Clarke, who has two previous alcohol-related convictions, quit his job and went to Spain to "camp" for several months, but did not take his medication.
When he suffered an injury he turned to drink "to cope" before boarding the flight to return to the UK.
The court heard Clarke had been charged for being drunk on public transport in 2001 and had another alcohol related conviction in 2002.
Rob Cowley, defending, said: "Dr Edwards described the defendant as suffering from severe anxiety and depression.
"The defendant had been working, he had been in a relationship. The relationship ended and he felt he could no longer keep on working.
"He stopped his job and went over to Spain intending to camp there for several months, but an accident prevented him from carrying on camping.
"He tends to turn to alcohol when things go wrong in his life and he feels unable to cope.
"He was recommended in the past to take medication, but he found that that had adverse side effects so he did not take medication with him when he went to Spain.
"But the defendant has said to me: 'I have made my bed and I have to lie in it'.
"He has come to court today expecting immediate custody. He is quite prepared to face up to what he has done and take responsibility."
