John Travolta
The aviation enthusiast - who is a qualified pilot - and his wife Kelly Preston were left devastated in 2009 when 16-year-old Jett died after hitting his head during a seizure while in the Bahamas and John has decided to pay tribute to him by bequeathing a G-2 Gulfstream executive jet to the Georgia Aviation Hall of Fame at the Museum of Aviation.

Chrissy Miner, spokeswoman for Robins Air Force Base, told the Telegraph newspaper in Macon that the plane is being prepared for a static display for an upcoming air show scheduled for April 28 and 29 and will then be towed to the museum.

Following Jett's death his parents set up The Jett Travolta Foundation, a non-profit organisation which has given away approximately $56,000 since it was set up.

Those who benefitted include a Scientology detox charity in Ocala, Florida, which received $2,500, the Starlight Children's Foundation and the No Limits Limbs Loss Foundation, who were both granted $5,000 each.

A further $2,500 was given to the Marion County Sheriff's Foundation while other donations included $250 to the Ehlers Danlos Syndrome Foundation - an affliction causing loose joints and hyperelastic skin - and $2,500 to the Central Florida Community College for a scholarship in Jett's memory.

Scientologists John and Kelly have two other children - Ella Bleu, 11, and 14-month-old Benjamin.
