Shoddy reporting. I think the author just looked up "jetpack" on the internet without comprehending anything. This jetpack is powered but sets of air breathing jet engines, the kind traditionally used to power modern passenger aircraft.
- callamdelaney 6y agoPerhaps the jetpack in the example video is, but this is not the jetpack that's been flying around LA International Airport, necessarily.
- davidhyde 6y agoThis is probably what the reporter looked up: https://en.wikipedia.org/wiki/Jet_pack https://en.wikipedia.org/wiki/Jet_pack Those hydrogen peroxide jetpacks have a flight time of 30 seconds so I doubt that's what this jetpack was since it was seen at 6000ft.
- bigbubba 6y agoJet: A collimated stream, spurt or flow of liquid or gas from a pressurized container, an engine, etc. The 'jet' in 'turbojet' refers to the stream of hot gas coming out of the engine. The 'turbo' in 'turbojet' refers to the turbine. Not all turbine engines are jet engines, and strictly speaking not all jet engines are turbine engines (though by convention 'jet engine' is taken to mean an air breathing turbine engine specifically, excluding rocket engines which also use jets of hot gas for thrust..) This naming convention is also broken by ramjet and scramjet engines, which breath air and produce jets, but do not have turbines.

- macjohnmcc 6y agoI think the story was that there was a flying person not a discussion about the technology. It would all be assumptions anyway as there are not photos or videos of the thing.
