Soon the loud passenger who's had too much to drink on your red-eye flight will be the least of your travel worries. Ryanair Airlines chief Michael O'Leary plans to launch an app that will allow passengers to watch porn on their tablets and smartphones during flight. Mr O'Leary told the Sun: "I'm not talking about having it on screens on the back of seats for everyone to see. It would be on handheld devices. Hotels around the world have it, so why wouldn't we?" Best of all, the app could also be used to gamble or play games in case you got bored during the speaking parts of your in-flight adult movie.
