One airline may venture into please-don't-go-ther​e territory and introduce in-flight adult movies.

That's the latest idea proposed by European discount carrier Ryanair, according to news reports. But Ryanair's CEO is known for crazy ideas that don't actually pan out, so no one's sure where he's going with this one.

British tabloid The Sun quoted Ryanair CEO Michael O'Leary as saying he wants to launch an in-flight service that mimics the pay-per-view setup offered by hotels. Passengers could gamble, play video games and watch movies -- even adult movies.

But thankfully, those movies wouldn't be displayed from an in-seat screen. Viewers would use a Ryanair app to watch movies on iPads and smartphones, the Sun reports.

"I'm not talking about having it on screens on the back of seats for everyone to see," O'Leary reportedly told the Sun. "It would be on handheld devices." He added that such a plan would be at least a year away because it would require a powerful and expensive broadband connection for the planes.

Ryanair has grown significantly in the last couple of years as the economy faltered, with passengers searching for cheaper flights. Analysts expect the airline to transport 75 million passengers in fiscal 2012 and 79 million the next year.

O'Leary has plans to make Ryanair even bigger -- and throw some unusual money-making ideas in to boot. The airline appears to be moving ahead with one O'Leary plan to install pay toilets on planes.

The airline is also looking into planes with standing-only areas. The idea is to cram more passengers on to a plane with "vertical seats" that allow people to be strapped in while standing up, The Telegraph reports.

So consider in-flight adult movies just another one of O'Leary's musings for now.
