But since Mikey-the-Pikey's unfortunate passengers are quite used to landing at tatty, run down airstrips in the middle of nowhere masquerading as 'airports', I doubt whether anyone in the back noticed that Ballykelly wasn't the intended aerodrome of arrival.
One of the best people-tube wrong airport cock-ups of recent times was the North West DC10 which landed at Brussels thinking it was Frankfurt. The passengers had seen the wrong destination on their seat back flight following maps (not an option on Ryanair's cheap and nasty seats, of course) and had alerted the trolley tarts, but the latter refused to contact the flight crew because of 'sterile cockpit' rules below FL100.....
The incident was later blamed on Air Traffic, would you believe!
