Porn played on big screen at Lisbon Airport

Travellers at a Portuguese airport giggled like schoolgirls when a porn film was inadvertently broadcast on a big screen TV above a baggage carousel.

Passenger Diogo Seabra who arrived at terminal one of Lisbon Airport around 2am on the weekend filmed the hardcore scenes as his bemused travelling companions watched and laughed.

"Welcome to Libson," one of the men watching the sex scene says in a video posted on Facebook.

Fortunately for red-faced airport officials there were not many people around to take in the lewd display because of the time the incident occurred.

"The monitors were connected in a generalist channel and, for a moment, no one noticed the type of film that was being transmitted," an Aeroportos de Portugal spokesman said.

The airports representative added that the problem was quickly noticed and rectified.

The bungle comes a week after a similar stuff-up at a Target in the US that saw porn played over the store's PA system for up to 15 minutes.
