The first report I saw of this said that it happened during a daylight rehearsal for the drone show. If that is the case it would seem even less likely to be jamming, IMO.
Just wondering why you'd build a drone that would use 100% of it's battery and switch off. Wouldn't it be designed to lose power slowly before the battery was exhausted so it would autoland safely and not commit suicide? Not a drone flyer so forgive me if this is a stupid question. 🙂
I don’t know this system, so I can’t answer your question. However, if the wind is strong enough, it can deplete the battery faster than expected, as the battery is constantly trying to stay in position as stated by the mission. A bit like your phone battery in the extreme heat. Hope this helps.
Alternative: Overheating? Maybe of the motors? Eg their coils or solid state devices burnt out (expensive "fuse"!). Due to (unexpected) _continuous_ max (or "turbo" i.e. beyond design-max) power just to maintain position. Idea inspired by your comment to Ralph2 (about why the drones didn't autoland before batteries died).
03:02 A red balloon momentarily visible, near bottom-right corner, released then floats leftwards - not that quickly, though wind speed at height tends to be greater.
Too simultaneous, too coincident for power failure. More likely to be drones ditching due to being unable to maintain location because of excessive wind.
Low battery would see the drones doing a 'return to home' surely? And to turn this off would be somewhat foolhardy, with hundreds of drones to manage. Also, WHY would the drone-show operator not ensure they had drones with sufficient battery life to last well beyond their show-time, even WITH the wind? Makes no sense to me.
Have you ever operated a drone light show before? Firstly, these drones work hard, so failures can happen with batteries, motherboards or GNSS units. A drone 'failing', is an acceptable part of operations. Secondly, the PIC would never launch a drone that had a 'bad battery'. Thirdly, conditions play a huge part with the performance of the drones. High winds can seriously deplete a battery of a drone working harder than others. You will never know if a certain battery health is bad, unless you can single that one out when it lands (difficult when managing hundreds or thousands). That battery would then be removed from the fleet. We also don't know what pressure the operator was under by the client. Stress on the PIC is common, and should be protected to make decisions based on a pre flight checklist. I hope this answers your questions. Our experience is vast, as we have done hundreds of these shows worldwide, in all environments.
Totally agree with you there Stephen. Bad weather conditions. Also, the drones falling will have knocked other drones .Hence, falling drones. Should have checked the weather. Only needed to look at the trees really 😂 Far too windy😮 I certainly wouldn't want that repair bill
If I was a betting man, the wind blew them into a preset geofence and the action on geofence interaction was "Kill". You will notice the swarm was moving towards land / people when the mass shut down started.
Considering the kind of operations they’re conducting, this is a good theory. However, I don’t think this is the case. Why? Drones hitting the geo fence is like kill all. Drones are falling randomly, rather than at the edge. A plausible reason though. Well done.
@@13BulliTs Not sure where my comment has gone that I just posted but I'd counted what I could see and got to 1500. There was an attached image which showed my counting but I'm thinking maybe because I linked to an external site that maybe TH-cam has deleted the comment. Going off what I'd counted and the fact that I couldn't get all the drones in one snapshot and there are dark patches likely to be of more than one drone I estimated altogether around 2000 drones. If you look up "how many drones at Cai Guoqiang’s Red Sail art performance failure" on Google and you'll see it says there were 2000 drones there so my counting was exceptionally close.
You are all wrong. This happened because the change in air temperature caused drone vapor to condense, creating small drone droplets that then fell to the ground. Next time just buy a dronebrella and move on with your life.
Yeah id say wind....jamming or hacked would all drop like a stone or in a line like it hit a wall because of a proximity of each other and b they will all be controlled by 3rd party software.....trees in background
I like the look of your skeptical spectacles 😊 This was an art piece with colourful pyrotechnics, with the drones forming the outline. It was performed after this incident. Maybe I’ll do a follow up video.
"Clearly have no idea" - actually he does have an idea, that's the entire point of the video. He doesn't have the answer, just an idea. Please enlighten us as to what it was then?
I agree 100% that the initial cause was the wind.
I'd never launch any of my drones in those conditions.
It looked bad from this video.
Great update Stephen 👌🏻🙏🏻
Thanks Tony.
Thanks for your professional take on this. Shows that you know what your talking about.
Thanks Roger.

This IS what any sane drone operator does.

Hope he had insurance 😮
100%
What is "killall" and what drone model was affected? How do you know if the drones have said feature without knowing the model?
All drone light show systems must have a ‘kill all’ function. This is a safety feature Incase manned aviation is a risk to the fleet.

Crap or old batteries that overheated due to increased drain due to the weather. imho
Batteries can go bad, as we all know, but not so many at one time.
The wind has put stress on them and they just couldn’t handle the task. Simple.
right above the water ...perfect timing
Above water is a preferred location for these shows. Less of a ground risk.
That's the location of the show... hardly unusual 😂
New Jersey syndrome? Electronics get zapped lately, by strange flying objects.
LoL

Things go wrong, no surprises here.
There's way more than 1000 drones there.
Probably. I'm not here to over dramatise the situation.
@ I wasn't either. Just made an observation.
@@MarkBowenPiano I just checked it and counting and seeing the grid, I highly doubt it was more than 1000.

A few hundred at maximum. Still, that is going to come to some hundreds of thousands of dollars in losses.

😢😢😢More plastic Pollution in the ocean....
And lithium batteries…
Looks nice
The explanation is easy: Elon Musk grew some strong interest in drone swarms recently, so they are already malfunctioning as if it was his enterprise.
😂😂😂 jam jam baby 😂😂😂
free drones for everyone
Woohoo

Yep
Our jamming was successful, it was done to show china that we now possess the only 100% jamming machine.
Give me one reason why you would be flying more than a thousand drones in the daytime? Also, there is no pattern. Looks more like an AI video to me.

emp
If it was EMP, all drones would fall instantly, plus, the phones filming would also die, so we wouldn’t have any video.
It was clearly a nuclear explosion.
lol........but buahahahahahahaha
you clearly have no idea what went on
What makes you say that?
