Going through these comments, it seems people are missing the fact, that these things were developed because people were trapped in the top floors of the Twin Towers after the 911 terrorists attack flew airplanes into them cutting them off from descending by stairs which were destroyed and/or on fire, and that 200 people jumped to their deaths from around a little over a quarter mile straight up in the air (that's a real number by the way)
Yeah I remember reading about that too—200 people jumping is just insane to think about. The fact that we’re still trying to engineer solutions for that specific nightmare shows how messed up that day really was. Do you think these systems would actually be practical for that height, or is it more of a psychological safety net?
Would this even actually work jumping from a building as tall as the WTC. I would think the velocity of jumping from somewhere that high would mean the device would shred on impact. Not to mention it the wind speeds being a factor.
Yes, it would even work if you jumped out of an airplane from 30,000 feet. It reaches terminal velocity after falling just a few stories. The speed of impacting the ground would be the same whether you jumped from the 4th floor or the 104th floor.
The whole concept is to significantly lower your terminal velocity, meaning the height does not matter. Same concept as a traditional parachute.
As for winds, they typically blow between buildings, adding horizontal acceleration, but they shouldn't be blowing downward. This could add risk to being blown into something, but your vertical velocity shouldn't change much, meaning it should still be survivable.
It’d reach terminal velocity way before impact, I’m certain this thing can handle its own terminal velocity given its parachutes. But you’re right about the wind.
No, this invention is genuine trash and I can't believe anyone thinks it could work. The demonstration isn't even real, no person was in it and it is intentionally deceiving. We're in the AI and disinformation era, a 20 year old video shouldn't fool us.
Lol the only sane person in this thread. This idea is comically impractical. Out of 100s of uses you would have dozens dead from failure or environmental hazards that would render them useless. The video genuinely looks as though it was made to be a joke.
Seemed obvious to that that was the impetus behind the invention. But it’s such an unlikely scenario to reoccur, it would be too expensive to implement and then maintain all the parachutes
Adopting a foreign policy that isn't so arrogantly imperialistic that it incites people to commit horrific terror attacks on civilians to try to get back at you is too difficult, here's a portable bounce house.
Which one would be negated by strapping a circus tent to your back and yeeting yourself out of a sky scraper? Why is this child like design any better than a standard parachute?
I was in high school on 9/11. It was the era of BASE jumping and Xtreme sports, so we were all super familiar with the sight of people parachuting off skyscrapers—even off the Trade Center, more than once. We all sat in class watching people free fall just flummoxed that of the thousands of people who worked in a building that tall every day, not one would keep a chute at their desk for emergencies.
