Awesome...

Some guy named Dean O'Malley was playing with a jet pack.

For four and a half hours...from Newport to Catalina Island. This is an unofficial new record for a jet pack flight in both time and distance.

Of course, this isn't exactly a superhero flight, for all that people keep using it as an example - the water propelled jet pack only works over water and has a ceiling of 30 ft...the length of the tube that pulls water up into the system. Still, it's a pretty cool toy.
