And the aircraft links don’t end there, Thunderbird was originally powered by twin 550hp Kermath V12 aircraft engines that pushed the boat to 32 knots.
It was kept in a 100ft-long boathouse connected to the house via a 600ft long tunnel blasted out of solid granite.
Whittell used the boat on the lake frequently for the two years that followed but when the USA entered World War Two in January 1942, Whittell hid the boat in its boathouse, fearful of it, or its engines, being requisitioned for the war effort.
The newly restored Thunderbird still lives in its original boathouse on Lake Tahoe
Age, ill health and an ever-more reclusive nature meant that the boat was little used after the war, Whittell eventually selling it to casino magnate William F. Harrah in 1962.
Harrah had it transported to his Automobile Collection restoration workshop in Reno where the original Kermath engines (which when removed had only 83 hours on them) were replaced with two V-12 Allison aircraft engines, each developing 1,100hp.
Harrah used it to entertain his casino high-rollers and show-headliners, such as Tony Bennett, Sammy Davis Jr., Frank Sinatra and Liza Minnelli.
Today the boat is restored and back at Thunderbird Lake Tahoe, now run by a charity called Foundation 36. It offers private excursions a few times a year in return for charitable donations.
