John Travolta is worried about global warming. He does at least acknowledge that his five jets and private airport might make him an unlikely ecologist, but... he needs them:
I'm probably not the best candidate to ask about global warming because I fly jets.
I use them as a business tool though, as others do. I think it's part of this industry - otherwise I couldn't be here doing this and I wouldn't be here now."
We're not sure about movie stars - we're including Travolta on No Rock by virtue of his late 70s hits, not his acting - but if owning a fleet of planes and building an airport on your land was essential to being in the film industry, wouldn't there be a lot more planes in the air? Is the need for your own air force now so crucial the cry to difficult actors has become "you'll never eat a personalised in-flight meal 40,000 feet above this town again?"
Still, Travolta has got a proposal that will allow all the actors to have a flock of jets and the human race continue:
Good thought, John - let's get the people of the South Pacific off to live on Jupiter before they drown, shall we? Let's take one of your special super space planess.
