John Travolta cradled his dead son in his arms and said he was "sorry".
Paramedic Tarino Lightbourn - who rushed 16-year-old Jett to hospital after he was found collapsed at the family's Bahamas hotel following a seizure on Friday - has revealed the actor broke down and clung to his son's body when he was told he had passed away.
Tarino said: "John went behind the hospital curtain, tears in his eyes. I could see the sorrow. I could see the love in his eyes for his son.
"When he was hugging his son he said, 'I'm sorry, Jett.' I think he meant, 'I'm sorry Jett, I did all I could do.' "
When Tarino arrived at the hotel, John was performing CPR on Jett - who suffered from rare Kawasaki disease, which the family say caused his fits - while his wife Kelly Preston looked on.
The medic has revealed the star was crying and praying as he battled to save his son's life.
Tarino explained: "He was crying, his eyes were red. I remember him looking up at the ceiling and saying, 'God, please help me.' "
Jett was pronounced dead shortly after he arrived at Rand Memorial Hospital in Freeport, Grand Bahama.
An autopsy was carried out on Monday and showed his death was caused by a seizure disorder. Jett was cremated this week and qualified pilot John flew his remains back to the family home in Florida yesterday .
The plane landed at Tampa, where a van marked with the logo of Church of Scientology - John and Kelly's religion - picked up the family.
A spokesman for the actor said a wake was taking place last night, with a funeral service planned for Jan. 7,2009.
John's biographer and friend Douglas Thompson has revealed the actor is planning to set up a charity in Jett's name, and will being campaigning against the use of domestic chemicals which he believes caused Jett's Kawasaki disease.
Douglas said: "I couldn't even begin to imagine the hurt and pain John must be feeling. The desire to protect Jett informed everything he did. The loss will be devastating."
