I found this [1] article when I started googling the people in the company, I thought this quite from their CTO Tomasz Patan was fun: Vi vill inte att folk ska köpa vår produkt och krascha den direkt, så vi har sålt till välkända personer främst i USA som skulle få för mycket skit om de gjorde dumheter med den which translates to (note: native Swedish speaker, but not a certified translator): We don't want people to buy our product and crash it straight away, so we have been selling to famous people mostly in the US, who would get too much crap if they fooled around with it" I enjoyed the directness of that statement. :) Also learned from the same article: - The maximum cargo weight including pilot is 100 kg, if you actually reach that then flying time is reduced to 12 minutes. - The battery pack is charged externally, i.e. not in the vehicle, so you can have spares and swap. - No mention of the battery pack's weight, but I guess you would have to be quite a bit below those 100 kg in order to have room for another battery. - New owners get a 2-day course (not a "crash course", I guess :) at Jetson before being allowed to take their new vehicle home.

I saw that video some days ago and thought "that would be a nifty way to get to work and back" ... 12 minutes flight time would actually allow that for me ... but not for a lot of others.

  12 minutes endurance is absolute madness to any pilot. No way to fly this thing within the current regulations. A fuel powered aircraft needs to land with a legal minimum fuel reserve of 30 minutes when flying visually (good weather only), in worse weather it's 45 minutes + the time it takes to get to an alternate airport in case of problems at the destination. So usually 1 to 1.5 hour of reserve/alternate fuel on top of the time needed for the flight itself.

    That depends under which class the aircraft will be certified, depsite it being electric I could image that it falls under the ultra-light class (I'd have to look up the exact Name under EASA so).
    - t0mas88 5y ago
      EASA doesn't have rules for ultra- and microlight aircraft, they're only in national regulations. So then it depends on what the country you're in decides. But even if you're allowed to fly with only minutes of fuel reserve. The big question is whether you should want to. When you're in a more basic aircraft, that didn't go through all the certification requirements that other aircraft go through, it would not be a great idea to skip all kinds of safety practices like fuel and alternate planning just because you're not legally forced to do it. You're then just increasing risks more and more, while this thing is marketed to non-pilot buyers that may not even fully understand the risks.

        This also doesn't look like it can glide or autorotate, so if you run out of fuel it's pretty much guaranteed to crash. Edit: I guess that eventuality is managed by the parachute system and a structure designed to handle the resulting "hard landing".

    Does this rule also apply to helicopters and other VTOL aircrafts? The alternate airport in this case might be a field or parking lot 100 meters away.
    - t0mas88 5y ago
      In good weather a helicopter is allowed to reduce it to 20 minutes. In bad weather the alternate must be an airport with the facilities to conduct an instrument landing, so definitely not just a parking lot. And the forecasted weather at that airport needs to be good enough from 1 hour before until 1 hour after the expected arrival. "Good enough" is defined stricter for helicopters than for airplanes.

They may have updated the article since you wrote your comment, but as of when I’m reading it, it’s attributing that quote to Peter Ternström, the other founder and CEO.

  Oh! Yeah, you're right ... probably my bad, apologies for mis-attributing. Can't edit my comment any longer.
