Today's Word is SUPERSONIC

Any speed over the speed of sound, which is approximately 343 m/s, 1,087 ft/s, 761 mph or 1,235 km/h in air at sea level, is said to be supersonic. Speeds greater than 5 times the speed of sound are sometimes referred to as hypersonic.

This is a video is a plane being supersonic.

This is what people from 1975 thought supersonic was going to be like.

And this is JJ Fad being SUPERSONIC on BET.

peace.
