He reached a velocity of 833.9 miles per hour, not feet per second, which is roughly 370 meters per sec. Also, the speed of sound would have been 672.5 miles per hour or roughly 300 meters per second. These numbers seem more plausible given what c would have been in his environment.<br /><br />Is that not correct?Eric Lanehttps://www.blogger.com/profile/01369165488555310380noreply@blogger.com
