Comedians including Dara O Briain have set a new world record for the "highest stand-up comedy gig in the world" in aid of Comic Relief.
O Briain joined Jack Whitehall and Jon Richardson on board a British Airways flight to perform the "smile high gig" in front of a captive audience of 180 passengers made up of guests and prize winners.
The plane climbed to 35,000ft for the 45-minute gig but O Briain, who performed last, joked: "I told the captain I'd bang twice on the locker like this when I was on - so he can take the aircraft to 37,000ft and beat Jack and Jon's record."
Whitehall said: "I was looking forward to today - after all, it's the only gig where people can't walk out. If you want to heckle you'll have to press the call button."
The gig, hosted on board a BA A321 aircraft flying from London Terminal 5, raised almost £100,000 for Red Nose Day.
British Airways Captain Brian Connolly said: "It was an honour to captain this very special flight.
"I'm proud to be able to say that I'm a Guinness World Records holder, and of course - member of the Smile High Club!"
