They probably have a grille or filter at the pump's inlet to prevent particulates and fish from entering. Nice invention, but probably more useful in a recreational pool/lake than in a firefight. You wanna be using all that water to actually extinguish the fire rather than raining buckets down on passers by and holding up one guy in the air.
Look closely behind him in the video. He's towing his pump with him. It looks like a modified jet-ski. I wonder if he could get up any higher with a longer hose?
It would be interesting to see what one of these could do, hooked up to a fire hydrant though.
@gerrylum: There is a point, when viewing the launch from the second angle it gives, where there is no pressure coming out and he just hangs there middair for a few seconds.
@Jacob Gold: Wow, yes they did, and they decided it was too dangerous and not practical. Also, they had a rack that seemed much larger than this one made out of regular 2 liter plastic bottles. This one looks smaller but with larger bottles, and therefor more pressure, but achieved at least 10 times more distance with an actual human being attached to it.
Mythbusters only successfully launch their dummy, Buster, about 5 feet.
@madog: The size of the bottle has absolutely nothing to do with how much pressure it can hold. During the Mythbusters test they found that a normal 2-liter holds 150psi while the big water water cooler jugs go boom and turn to shrapnel at like 80.
You can tell it's fake, just look at how he flies... it's not right, too linear. Looks like a cable pull.

He'll be OK. His whole body is a crumple zone. Very safe.
