Ladies and Gentlemen, This may just be a pet peeve but…

A “Jet Pack” and a “Rocket Belt” two totally different personal aircraft approaches, and it really gets my gyroscopes un-spun when people mistake the two. The 1961 Bell Rocket belt is the most popular, being flown at the Pentagon and even being featured in the James Bond movie “Thunderball.” The Bell Rocket belt is fueled by Hydrogen Peroxide and by use of a catalyst, is turned into steam and oxygen at a very high temperature, which expands through a rocket nozzle. Whereas the Jet pack is usually powered by Jet-A or Kerosene, which spins a turbine forcing air in the downward direction. Jets are much more difficult to manufacture, and are very heavy (But are able to fly for longer periods of time); whereas the H₂O₂ rocket is simpler to build and less of a hazard to the user (Hydrogen peroxide is usually stable unless acted upon by a catalyst); but only have a flight time of ~30 seconds.

So that’s why my fins fall off when people mistake one for the other.

Sorry for the long rant.
