I just finished reading an amazing article about a man who was reported to have broken the speed of sound without the use of external power or an engine of any kind.
several of us talk about use of a TRE, turbo, NOS, etc. to try and break 190MPH - but this guy did much more than that.
Taken from the website:
Speed of a Skydiver (terminal velocity)
"On 16 August 1960, US Air Force Captain Joseph Kittinger entered the record books when he stepped from the gondola of a helium balloon floating at an altitude of 31,330 m (102,800 feet) and took the longest skydive in history. As of the writing of this supplement 39 years later, his record remains unbroken."
"According to Captain Kittinger's 1960 report in National Geographic, he was in free fall from 102,800 to 96,000 feet and then experienced no noticeable change in acceleration for an additional 6,000 feet despite having deployed his stabilization chute. This gave him an unprecedented 3900 m (12,800 feet) over which to accelerate."
"At nine-tenths the speed of sound, Captain Kittinger holds the record for the greatest speed attained by a human without the use of an engine. The standard value of the speed of sound in air at 31,000 m is 670 mph.
