Prof. Christiaan Barnard, who performed the world's first heart transplant, claims that his friend Diana could have been saved following the fatal car accident. In 50 Ways to a Healthy Heart , Barnard writes that if Diana had been brought to a hospital immediately after the accident she might have been able to survive. Instead medical personnel worked on her at the scene of the accident for two hours.
In speaking for the first time about a letter he received from his sister only a few days before her death, Earl Spencer swats away rumors that Diana was pregnant or engaged. "...I certainly don't think she'd have married [Dodi Al Fayed]."
