UPDATE April 18th, 2017 - This previous video was taken down, I found another cut of it by quy Thung, who has charmingly uploaded it three times. Thanks for grabbing it guy!
This lunar distance calculation made by Shaquille O'Niel was not only extemporaneous but it was at the behest of Charles Barkley live on TNT.
Shaq guessed a 10 1/2 hour flight to the moon. 10.5 hrs at ~500mph = ~5,775 miles.
Interestingly, this is not too far off from the current Flat Earth contention of the solar distance calculation being conjectured at a little over 3,000 miles. Specifically, according to the video below, 3391.444 miles. Others have calculated as low as 3,100 miles.
At the end of the video, Shaq lowered his guess to 7 hours, which if a plane is going 500 miles per hour, is 3,500 miles, even closer to Flat Earth predictions of the solar altitude.
When you consider the purported 237,000 miles as the estimated distance of the Lunar Body and the purported 93,000,000 miles for the estimated distance of the Solar Body, any distance approximation below 10,000 miles is vastly and extremely shorter than either so as to essentially become the same approximation.
Flat Earth Theory also contends a solar and lunar body of equal size, hence the capacity of the Moon to eclipse the Sun.
