John Travolta has flown emergency supplies to Haiti.

The 'Grease' actor, who is a trained pilot, flew the specially-borrowed plane to the Caribbean nation's capital Port-au-Prince to help the 1.5 million people who are believed to be homeless in the capital following the earthquake.

Travolta flew in the Qantas Airline aircraft full with ready-to-eat rations for survivors of the disaster with his wife Kelly Preston.

Speaking on his return flight, the 55-year-old actor said: "We have an ability and a responsibility to help make a difference."

Last week, he said: "I have arranged for a plane to take down some volunteer ministers and some supplies and some medics.

"I hope that inspires others as well. It's needed."

Travolta is among a number of A-list celebrities to take action after the disaster struck.

Last week, George Clooney fronted a TV telethon to raise money for the Haiti relief effort, with celebrities including Reese Witherspoon, Justin Timberlake, Madonna and Cameron Diaz taking phone donations totalling $58 million from the public.

Meanwhile, a charity single is being organised my music mogul Simon Cowell, with a host of singers including Rod Stewart, Cheryl Cole, Mariah Carey, Kylie Minogue and Robbie Williams recording REM's 'Everybody Hurts'.
