The question of upper body strength requirements was posed back in Post #26 on 29th September. The question remains unanswered. I looked up the Bournemouth jet pack demo and found this video:
Apparently two jet pack fliers were involved in the demo, one of which, hits the drink at 20 seconds into the 40 second video. I've looked at other discussions of the video, and some of them fail to mention the unplanned dunking and otherwise ignore details of the "demonstration".
In this age of all too realistic CGI, I'm afraid that I'm a bit of Doubting Thomas with respect to all of this. Has anyone seen technical/engineering details of the design of these jetpacks? It would be interesting to see how the thrust is divided among the 5 jet engines, and how thrust control is managed ... among other details.
Cheers,
Grog

As for the details of the system, have you tried searching for their patent applications, both in the UK and worldwide? They might reveal some of the technical details.
This is very definitely a ‘thing’. However, as has been pointed out for multiple reasons,

...then you've seen a group of people (including the casualty) who need a SAR helicopter. Of course, GNAAS are known for being extremely reluctant to call in a rescue helicopter...

Jetpack rescue is...go!

Hot on the heels of a post asking for historical info of the first helicopter rescue, comes the dawn of first jet pack rescue! Well, a trial at least.
In regard to fuel as dangerous goods cargo, could the pack be transported in a typical air ambo without any additional paperwork?
I'm thinking cloud cover allowing helicopter access to the base of a mountain to drop off jetpac pilot. Such weather windows unlikely in Wales? Video says only 6 days training so maybe there will be enough of these kits around to be deployed by road?
Less or more physically/mentally arduous than climbing to the patient?

He goes to the patient with his jet suit and do what ???, he does not have one pound of equipement ...!
That is what a paramedic needs:
2 large backpacks full of medical supply of all sorts so heavy they need to fly a B3

Agile - “He goes to the patient with his jet suit and do what ???, he does not have one pound of equipement ...!”
- according to other reports available, they have the capability to take “10 to 15kg of medical kit, including a defibrillator and patient-monitoring devices which are strapped in pouches on the pilot's legs and chest”
Bravo73 - “They did something similar a couple of years ago in the Lake District”
- again, according to other reports, it is apparently close to ready for operational use this summer in the Lake District.

I think you'll probably find that the Norwegian approach of longlining the air ambulance paramedic into difficult incident locations and then using the SAR fleet for extraction is safer, cheaper and quicker.

I'm genuinely curious how fuel level and endurance is indicated/calculated, I'm certainly not an expert on jet pack operation, but I'm thinking the engine out characteristics are quite limited. A stopwatch would definitely be an MEL item.

You can carry pain relief, a splint and some intravenous fluids which have their benefits for an hour or so but I am not really sure why it will be that much faster than a helicopter. Then there is the issue of what happens if your lowly paid paramedic who has now also undergone flight training isnt up to speed on weather and gets weathered in. Add in the issues of navigation and a low hours jet paramedic being able to actually search with limited flight endurance and you have all the ingredients for another medical nonsense article.

The following was posted by Two’s In on the last thread about this nonsense and in case they don’t get round to re-posting it I will as it’s hilarious……..
"...the Board determined due to dense fog near the summit, that the jet pack operative's glasses had become steamed up. In an attempt to wipe his glasses, the operative became temporarily inverted which caused the jet efflux to ignite his starboard trouser leg. Distracted by the burning clothing and momentarily disoriented, it is believed the operative incorrectly selected the "TOGA" power setting button which was adjacent to the "Demister" switch. The sudden increase in power caused an immediate bowel evacuation, the secondary effect of which was a CG shift which then pitched the operative back to the vertical. The fecal weight loss combined with the TOGA setting generated an immediate high velocity climb. The increased power setting consumed the remaining fuel at a far higher rate, and the jet pack flamed out shortly afterwards, while still firmly IMC. The parabolic arc described by the jet pack led to the operative arriving in a near vertical dive at a high velocity some 20 feet from the stranded hiker. The hiker reported the operative was still on fire with steamed up glasses shortly before impact. Rescuers were able to use a spatula and cigar box to recover the remains. The hiker walked down from the mountain unharmed."

It's the middle of summer. No rain for months. The thick long grass is very dry. Someone breaks their leg on the mountainside while hiking.
Along comes our paramedic hero and, as they flare for landing, they ignite the grass and turn both of them to toast.
