".. broke the sound barrier in water. That's nearly 5400 kilometres per hour--or 1.5 kilometres per second . [...]"
Perhaps its my poor understanding of the english languaje, but one thing is true: Sound doesn't travel at 1.5 Km/s. Lets see: 360 m/s = 0.36 Km/s = 1296 Km/h != 5400 Km/h (wow!)
Oops, forgot the fundamental rule of Science: all constants are variables
So, lets do it again: 1 Km ~= 1000 Km, say 250 m (aprox). So: 360 / 250 = 1.44 Km/s = 5184 Km/h which is aprox. equal to 5400.
