I have been studying videos of swimmers and find what was once called the "S" stroke has almost disappeard.
I have noticed that flyers use it. But crawl swimmers have modified it so much that it is almost gone.
Has it been replaced completely or was it an optical illusion? Did underwater film show us it did not exist.

Sound of speed in Water is something like 3000 Mph or is it 3000 knots per HR??
In fresh water, sound waves travel at 1482 meters per second (about 3315 mph). ... The exact speed of sound in steel is 5960 meters per second (13332 mph)
