He can circle the earth 8 times in one second !!!
In a few issues of DC comics in the 70's, Superman and the Flash raced around the world to see who was the fastest-------they had to stop along the way to make their usual heroic saves of humans, so the pit stops they had to make slowed them down-----but, when they raced toward the finish line, they both were pouring on the speed, and it eventually ended up a tie.
But, in a issue of Flash comics, it states the Flash can circle the earth 8 times in one second, so, Superman should be able to do the same thing !!!
Pretty fast , eh ?
Also, in the first Superman movie with Christopher Reeves, Superman is flying around the earth so fast that he reverses the spin of the earth, thus turning back time------it looked like he was easily going 8 times a second around the world easily.
Bottom line, Superman had to be taking the Gakic/Luekic/Creakic/Anator-P70 stack.
Dont you agree Lee ?
