20 Things You Didn’t Know About Thunderball (1965)
4. “And He Strikes Like Thunderball!”
As mentioned, retired US Air Force Lieutenant Colonel Charles Russhon used his military connections to procure an experimental rocket fuel so that the filmmakers could destroy the Disco Volante - now a high-speed hydrofoil - when it crashes into the coral reef and explodes.
However, the fuel was so powerful that, when the explosion was set off, the reverberations from it blew out the windows in Nassau’s Bay Street approximately 30 miles away! This was because it arrived late and John Stears and his crew had not been able to test it.
When the Disco Volante was detonated on location, it simply vanished, leaving Stears and his crew nonplussed, wondering where the wreckage was. They soon discovered that it was raining down upon them from above and they dove out of its way; fortunately, no-one was hurt during filming.
Stears won an Academy Award for Best Visual Effects for Thunderball, making it the second Bond film to win an Oscar.
