Jet suits and jetpacks
Also known as Jet suit, Jetpack, Personal flight suit
Jet suits and jetpacks are wearable frames that carry small jet engines, letting a trained person fly for a few minutes. Trials by an air ambulance service and a navy show the idea can work, but short flight times, high cost, noise and unsettled rules keep use niche.

In plain language
A jet suit is a wearable frame that carries several small jet engines, usually fuelled by kerosene. The engines push a stream of hot exhaust downwards, which lifts the wearer off the ground and lets them fly short distances over rough ground, water or steep hills.
The appeal is speed over difficult terrain. In 2020 a Gravity Industries pilot flew a suit from a valley floor in the Lake District to a simulated casualty site in about 90 seconds, a climb that the charity estimated would have taken around 25 minutes on foot. Flights are still short, though, and the suits need trained pilots, fuel and careful safety planning, so they remain a specialist tool rather than an everyday form of transport.
Technical explanation
Current suits use small kerosene-fuelled gas turbine engines. A 2018 NBC News report on a suit offered for sale described five small kerosene-fuelled turbine engines, two on each arm and one on the back, and reported flights of up to four minutes, citing Reuters. In 2022 the company's founder, Richard Browning, was quoted as saying the suit produces up to 144 kg of thrust. A 2021 Forces News report on the Royal Navy trial gives the suit's power as 1,050 brake horsepower and its speed as above 80 mph, and says it is technically capable of reaching 12,000 ft. These figures come from the company, the press and the trial partners, not from independent test reports.
Fuel use and endurance are the least well documented parts of the picture. A 2015 IEEE Spectrum article on the earlier JB-9 jetpack from Jetpack Aviation reported that it sucks down just under 4 litres of fuel a minute from a 38-litre tank and will fly for at least 10 minutes before running out of fuel. The same article said the JB-10 was then in test flights but gave no fuel or flight-time figures for it. Across the sources reviewed, quoted flight times range from about four minutes to about ten minutes, depending on the model and the report, and none of the sources gave an independent measurement of fuel burn for a jet suit.
Noise is also poorly measured in public sources. The 2018 NBC News report quoted the company founder comparing early jetpacks with early motor cars, which were noisy, but gave no decibel figure. No independent noise measurement was found in the sources reviewed, so any single decibel figure should be treated as unverified. On regulation, a CAA spokesman told the BBC in 2017 that a new category of regulation may be necessary, and that a pilot would almost certainly need some kind of training and a licence. The sources reviewed do not show a final UK rule for jet suits.

Ørsted describes offshore wind uses, such as on-site triage and moving technicians to and from structures, as potential applications rather than proven ones; its 2022 trial was onshore.
Sources: [3]Limitations and open problems
- Flight times are short. The sources quote roughly four to ten minutes, which limits range and the time a suit can spend on a task.
- Fuel use, endurance and payload for current jet suits have not been published as independently tested figures. Figures in the press come from manufacturers, trial partners and reporters.
- Noise has not been measured in any independent public source reviewed, so its effect on pilots, bystanders and neighbours is not established.
- Regulation is unsettled. In 2017 a UK aviation regulator spokesman said a new category may be needed, and the sources reviewed show no final rule.
- Cost is high. NBC News reported a price of £340,000 in 2018 for a suit that was one of nine for sale. No later price data was verified.
- The trials are early stage. The 2020 air ambulance test used a simulated casualty, and the 2022 programme described itself as being at an early stage, with no published figures or outcome data.
Possible future uses
Ideas, not predictions. None of these has been demonstrated.
- Rapid vertical access for ship boarding, if military trials show the suit is quiet, reliable and safe enough for operations.
- Offshore wind technicians moving between turbines and platforms, which Ørsted describes as a potential use rather than a proven one.
- Emergency first response in mountain and flood areas where roads are blocked, once flight times and pilot training routes are proven.
