Even if it's not Rossi, whose design has been years in the making, I think a copycat is most likely here. Rossi's wing operates at 4000+ feet and 189mph, which is comparable to jets slowing down on long final. Those hobby jet engines are very expensive but off the shelf, and anyone can build a wing in their garage. The FAA would classify it as an aircraft (already has), and would like to talk to this operator.
I think you can rule out the multirotor bathtubs for now.
- sandworm101 6y agoIt is also odd that they said "in a jetpack" rather than wearing or riding on/under a jetpack. Might this also be a very small but conventional aircraft? Might it be a mannequin mounted inside a smaller drone? Size gets distorted in these situations. (FYI those hobby jets are one option, but there are considerably more capable small jets available, mostly used for cruise missiles and heavy drones.)
- imglorp 6y agoYeah, that's plausible too.
- thursday0987 6y ago"in a jetpack" is just a colloquial way of saying "wearing a jetpack". other examples of this type of language include: "Do you see that man in the suit over there?" "the suspect in body armor was described as being 6 feet tall." "man in an orange shirt" is the title of a popular pbs show. etc etc etc.
- pc86 6y agoAirline pilots typically earn their 1500-hour minimum for their license in "small but conventional aircraft" so the odds of them mistaking one for a jetpack is approximately zero.
- sandworm101 6y agoAnd I probably have 5000+ hours driving cars. That doesn't mean I don't occasionally confuse one type of road vehicle for another, especially when dealing with odd/rare types.
- cglace 6y agoYou often confuse motorcycles for cars?
- mstade 6y agoAt night, sure. Many times I've met a car with a broken headlight, only realizing it's not a motorcycle as we're passing. I don't know if this happened at night, but visibility can be reduced for other reasons as well.
- pixelbash 6y agoIn those cases were you certain what you saw was a motorcycle before realizing otherwise? Or did you wait until you passed to be sure?
- IgorPartola 6y agoThis one is scary to me, as a motorcycle rider. The other one that’s not fun: some motorcycles have two separate headlights on the front (low and high beams) and can be wired so that both can be on at once. What are you looking at? A car that’s really far away or a motorcycle that’s really close? Please watch out for motorcyclists. The blindness people have for us is astonishing. And terrifying.
- hazeii 6y agoI've had that on a bicycle. The bike had two small side by side halogens on the handlebars, I was on a main road when a car pulled straight out of a side turning and into the side of me. I released afterwards he'd glanced down the road, seen two small lights and assumed it was a car far enough away for him to pull out. On motorbikes I've had drivers in side roads look me in the eye and then pull out. On occasion I've ended up having words, and it's always "Sorry mate I didn't see you".
- bluescrn 6y agoThere’s at least one video out there of a ‘flying inflatable doll’ attached to a drone. Could be something like that...
- consumer451 6y agoAt this point, this feels like the most correct speculation.
- Waterluvian 6y ago“I’ve got a phone number for you to write down. Are you ready to record it?” “Uh...no?” I imagine a jet pack forces some interesting takes on related technology that pilots are used to having access to when in a cockpit.
- dpifke 6y agoFor the non-pilots: if ATC gives you a phone number to call after you land, it means you really screwed up. (It's the number for the supervisor, who is thinking about filing a "pilot deviation report" with the FAA.)
- braythwayt 6y agoThe pilots I know describe these calls informally as, "Mr. Braithwaite, would you step into my office? Bring your license, and a match."
- OJFord 6y agoThis thread spurred me to listen to some clips, and I just happened across an 'I'll give you the number when you're ready to copy' example: https://youtube.com/watch?v=mUSUXnr4dSo https://youtube.com/watch?v=mUSUXnr4dSo

- taneq 6y agoZapata’s Flyboard Air has much the same capabilities, as doors the Gravity Industries suit.
- imglorp 6y agoSeem not, maximum 100 mph (edit: for flyboard. Gravity Industries max is 84 mph) https://atlanticflyboard.com/flyboard-air https://atlanticflyboard.com/flyboard-air https://gravity.co/experience/ https://gravity.co/experience/
- taneq 6y agoOh cmon, 16mph difference in top speed is still "much the same". Yves Rossy's wing: Optimized for forward flight, has VTOL capability, bulky. Zapata's flyboard: Good middle ground, VTOL with decent speed, restricts ground movement. Gravity jetsuit: Optimized for hovering, lightweight, can walk in it. They're all doing much the same thing though, strap some jets onto a human and allow them to fly with VTOL.
- sudosysgen 6y agoa 400N jet engine is now only 6000$. Building a wing with a TWR > 1.0 would only cost about 18 000$ in engines, which is really not that much.
- sandworm101 6y agoYou don't need a TWR anywhere near 1.0. You need that to take off vertically, but if you are willing to jump out of a helicopter you can probably get away with TWRs closer to 0.35 to maintain level flight.
- sudosysgen 6y agoYes, indeed, but a jetpack specifically refers to a device that is able to hover and take off vertically. But yes, you could make it even cheaper and lighter then, but would need something to help you take off.
- jandrese 6y agoEven the Helicopter may not be necessary if you can start with a BASE jump. Or set up a catapult.
- phs318u 6y agoPreferably an ACME catapult.
- wile_e_coyote 6y agoNo. Their products are terrible, please, just trust me, I've tried them all.
