John Travolta and his wife Kelly Preston, indignant by the lack of response from American authorities, decided to flew with their personal jet to deliver five tonnes of food to the victims of Hurricane Katrina.

Travolta, a licensed pilot, flew to Baton Rouge, carrying the food supplies for the evacuees and more than 400 doses of tetanus vaccines. The couple then toured the flooded city of New Orleans and visited rescue workers and shelters for the victims.

Travolta said: "What we've seen in the shelters is wonderful, because people are being taken care of. What we've seen in the city is disastrous."

Amongst the other celebrities who visited the affected areas are Oprah Winfrey, Macy Gray and Sean Penn.

And Celine Dion, Nicolas Cage, Jerry Lewis, P.Diddy and Jay-Z donated $1million to the cause, while Britney Spears has offered a message of support on her website.
