As someone that acted as PIC for a Drone show, (long story), I had to learn a few things about them. They didn't all fall at the same time. One dropped quickly so that could have been a battery failure. More than likely though, it was a software setup error. In most of the software, there are two boundaries, a soft one, where the drone tries to correct, and a hard one, where it goes down. I would bet that the operator (programmer), who was not the PIC, set up the hard fence where it interfered with the show area It's not that hard to do. There are multiple people involved and the PIC doesn't fly them, a ocmputer does. It also looks like there could have been magnetic interference at the drone setup spot, judging by where some of them went (a lot of magnetic interference due to a lot of iron near these harbors, especially around piers and walkways). These things all calibrate to compass at the same time and are RTK located and controlled through a computer. If you don't get good magnetic calibration, you need to abort. Without more information, these are obviously guesses though. The PIC makes to ultimate deciaion to go and whether to continue or drop them in the drink but normally doesn't design the show or set up the fences. There is a lot of pressure to say go, on everyone in the crew, including the PIC. There is a lot of money involved, future work opportunities, etc and events people are not always so forgiving if you abort. You need a PIC that will say no. Luckily, I didn't have to. The staff I was working with were very professional and experienced.
Excellent information. Thanks for sharing it. Pinning for others.
1) how can you be PILOT IN COMMAND if you are not in control ? 2) the PIC is responsible for the preflight - Compass cal is done before takeoff . If something is no GO then why is PIC taken off? scary that PIC is not aware of his flight parameters. This is the prime example of commercial pressure. AAIB report will make an interesting read
@@helinick81 It sounds like you think the PiC is actually flying the drones. There is no hand controller for these drones. The PIC does not fly them, the computer does. It's like a mapping mission, but with several hundred drones flying within feet of each other. The computer has to keep track of where all of them are, deconflict locatoins, set the colors, and direct them into where the designer of the show wanted them without hitting the other ones. A person can't do that. The PIC is responsible for the overall process, but does not do everything himself. The PIC has to make sure the calibration was successful, not place and move each drone to make it happen. As PIC, you are looking at the computer checking them and verifying with a light on each drone. You look at the process of checking and charging the batteries, not do each yourself, You have others keep people clear of the takeoff/landing site. You have Coast Guard clearing the waterway, police involved for crowd encroachment, but you don't do everything yourself. There are multiple processes involved. There is a computer checklist, and I had my own. Once it starts though, the PIC's only decision is whether to abort or not and that usually involves drones getting wet. I also didn't say that the PIC didn't verify that the calibration was done. I only mentioned it as one potential failure point. For example, a misdirected or problem main antenna could causedsome of it too. If the software doesn't detect some of the problems, you won't know until some drones don't go to the place you expected. A PIC is more like a conductor. That is why team management is considered important by the FAA.
As a fellow drone show pilot in the UK it looks to me like they were struggling to get the fleet home which could happen for multiple reasons and at 3:10 in looks like they decided to disarm them. It will be interesting to read the AAIB report when it is published. It's a really tough situation to deal with when things dont go to plan with this many aircraft in the air and I feel for them.
@pdfp24 Thank you for that feedback. It has been particularly fascinating to hear from people working in the niche. As you state, the report should be interesting but at least it ended with an extra show for someone riverside rather than any safety issue.
One rule for one. Another rule for another.
You pay TFL money, you can do what you like... even pollute (£12.50 to drive in London with a "polluting" car).
I'm interested to know what about the ones that sank. Were they able to get them out, or were they lost. Because that one with the red light looked like it sank rather quickly.
Thanks for sharing. 👍👍👍
Yes it would be very interesting to know, especially as there were so many and it is a fast moving part of the Thames.
The Thames river near tower bridge in on average only 1.5 metres deep at low time, so a good chance they could have recovered them depending on the current strength
It’s more likely a DJI pilot plugged in nearby and it caused the failsafe 😜
We have solved it 🤣
Definitely something went wrong, nobody in their right mind would decide to land on water and risk writing off multiple expensive drones unless it was some sort of emergency.
100% agree.
When the drone light show was working it looked awesome I thought. Also it shows the the Risk Assessment put in place by the organisers when planning this worked really well. For what ever reason this "failed" no one as far I know was injured. I think that as Ai becomes more implemented into every walk of life this wont happen, the drones will figure it out for themselves and choose to return to home or ditch on safety grounds.
We had the same thing happen in Melbourne VIC about 4 Months ago that time 100 or so drones fell from the sky, reports released after the event said that it was caused by a GPS fault triggering the fail safe. They spent days fishing drones out of the Yarra River and the never recovered all the drones so some may have come down on land in the Melbourne Event.
Hey Trevor! Absolutely. Recovery would usually be there for one or two drones. Will be interesting to read the report when it comes out.
Sickens me that a hundred drones can fall like rain yet companies receive no sanction, yet if a hobby flyer makes his drone safer by upping the transmission power his life can be made pure hell.
Or God forbid you fly FPV, so you can actually judge where you're going
How can your life be made hell if you up the transmission?
@@WhatsWrong221 cops being cops.
how can they recover drone from water wouldnt the drones just sink too the bottom ?
The drone starts flashing brightly red/white and does have some buoyancy. Not sure how they would recover this number of drones as usually it is one or two maximum.
They are just testing out the next evolution of drone shows... Underwater light shows. Seemed concerning that the drones seems to be sinking, seems like taping some foam or something to them to make them float would be standard procedure if flying over water.
Hey Mike! Underwater light shoes are the way forward! I like the idea of giving the drones buoyancy. Especially as they operate near water so much.
Not so good in a tidal river, they'd be out in the North Sea in a breath!
Good report Shaun
So... what is the pollution risk from the batteries?
Minimal if recovered. Not sure in terms of unrecovered units. Although I expect all if not vast majority were scooped up pretty quickly.
Lithium hydroxide. Think of sodium hydroxide (caustic soda, drain cleaner), but slightly less potent.
Probably clean the water up a little. @@fredfred2363
Has anyone asked SkyMagic what happened. The errors could well be glitches in the flight controller which trigger a controlled descent. It’s not counter UAS.
that police jammer test worked out very well it even spoofed "land now" hahahaha
Brown out from a high energy CME .? There was a large one thursday followed by the largest one since 2012 on Friday .29th..
The port authority in London have put some more major hoops to jump through if you want to fly a swarm over the Thames because of this incident. Rightly so I think,but still a PITA.
I hadn't heard that update yet. Thank you!
How can they return home if the gps is jammed?
I think it's more likely to be weather related and poor battery management, somebody forgot to charge them up, maybe they've all been left standing for long periods fully charged?🤔
That combined with the high gale force winds of storm Gerrit and low ambient temperatures, it's no wonder they were dropping out of the sky⚠️😲😳😁
I certainly doubt many drones were recovered, that first red one was floating for a few seconds but you could clearly see it sinking deeper and deeper!
Then when more and more started dropping plus the large group at once, you'd need multiple boats and lots of people to recover them that quickly.
I doubt they had more than 2 boats out and 4 people to recover them at most.
Going off how quickly that first red one sank, they might have saved a couple at best?😳😁
You can see as the camera pans up and down the river, there are no boats in mid stream anywhere⚠️🤔
Whichever way you look at it someone messed up and won't be doing anymore drone shows⚠️😳😁
It wont be down to battery management. As drone swarm pilot I know that the system wont let you launch the swarm unless the batteries are above a certain percentage.
At 3:10 a load of UAVs drop at the same time,this very much suggests that they were either sent a disarm command or they hit the "hard fence" which disarmed them.
@@pdfp24 Weather related then, either the drones were blown out of their 'fence', or no matter how fully charged their batteries are, if it's gale force winds and low temps, those batteries are going to discharge a lot quicker than usual.⚠️😲😳
@@pdtech4524 that was my first thought but high winds are usually pretty apparent in a swarm. It moves through them like a wave and you can physically see them all pitching into the wind which you don’t see in this video. The wind could have died down when the filming started maybe.
There’s no way of really knowing until the report comes out 😊
Nothing wrong that more regulation can’t fix 😂😂😂😂😂
I cannot even answer this 😂🤣🤣
@@Geeksvana it was tongue in cheek Sean 😂😂😂
'Bubba, did you charge the batteries?'
Where are the drones coming from ?
I mean which supplier ?
Sky magic
Don’t know if you know David Bombil’s channel with interviews with OTW “Occupy The Web”. There was a discussion that radio waves can be hacked. Could happen but also wondering if the radio signals could be monitored for packet errors.
So the "experts" are now trashing amateur uav pilots reputation.
Hope the UK FAA(CAA) took note! 😂
What should happen in a hurry? Could they RTH 500 - 2,000 drones all together?
Interestingly it might be a controlled descent, but i wonder if they had control over them... a serious H&S concern and CAA reportable event if they could only but watch..... i noticed on the night they created targets and sent fireworks at them. I wonder how close they were because it may have just been the angle recorded 🙉🙈
Hey Tazzy! Interestingly, in previous years, the drones were recorded separately and digitally added to the fireworks live on TV.
I just noticed I started my main reply with the same word as you. Have you been subliminally programming my brain again Tazzy??
@Geeksvana well I learnt something today 😂
@Geeksvana frankly, no I didn't 😂
Lets see what the CAA report comes up with.
Hey Adrian. It will be an interesting read. Happy new year sir!
When Robert met D.J all hell broke loose!!😂
They probably lost their Network ID connection.
😂 No RID, no flight...
Wow what an absolutely expensive night for someone. Wonder if they can claim on their insurance
Insurance company: You lost how many drones in the Thames?
I dont think Ive ever seen a mass drone show in which multiple drones did not fall from the sky
Out of interest, Would they need to report this incident to the CAA?
Yes. I would also expect they would need to demonstrate it wouldn't happen again or they have dealt with the issue to then fly again for the main event. This would be under a swarm OSC authorisation and emergency issues would be covered in their ops manual etc.
this is a major incident, the AAIB will certainly take a look. Those are near misses. a MOR will certainly be raised.@@Geeksvana
Swarm technology, which is what these light shows are, do not have a pilots that control the flight of the drones. The control comes from computer software and RTK hardware which the operator is responsible for. In order to facilitate these shows the operational area is much greater, due to the number in the swarm, and the area within the RTK boundary must be kept clear. The risk of failure is much greater.
Why didn't somebody ask the drone show producers what went wrong?
We did. They preferred not to comment on it publicly for a couple of understandable reasons.
@@Geeksvana Ahhh - thx.
It raises an issue. During large public events in Central London it might be expected for the security services to deploy drone jamming tech to prevent a terrorist attack using drones. If drone shows become more common then this might leave a gaping hole that terrorists might exploit. I do not know which frequencies the display drones use, is it encoded wifi like DJI use or something else ? The drones might be programmed to be autonomous and only need GPS, however, if GPS starts wandering as happens then so will the drones. Perhaps Sean you can interview the company or manufacturer of these drones to find out in detail how that actually do these amazing swarm displays and ask them what went wrong in the rehearsal. ?
The issue of jamming is interesting but sadly we are unable to discuss much of what we know on air as this would expose tactics used by police. However, the tech currently used in the UK is sophisticated and would be able to differentiate. Ultimately if there was a threat, I would expect authorities would also prefer to take everything out of the sky if the only option.
Fancy inviting one of these companies on, Sean?
Yes! Absolutely.
Some people have been "experimenting" using 4 and 5G comms, with data transfer using regular cell towers.
And there are other ways too, which, correctly, we'll not discuss in public.
GPS is not accurate enough to be the sole positioning reference - On some behind-the-scenes vids of shows you often see many special antennas laid out around the area
Sabotage , they don't even get chance to enter RTH .
When so many go wrong, it's not by accident
great video
What about russian GPS disturbance?
I still do not see how this is safer then flying a woop behind a tree, also not a chance someone can see all drones and same time, let alone point one out saying which one is misbehaving, also new rules did come in back in January last year that you need to know the Orientation of the UAV just by looking at it, how can this be done with these, as other said rules are BS. That is why I do not bother with the BS ones myself
Happy flying mate
The orientation never changes during the flight so that would be an easy one to determine!
ok by looking at the drone what was the orientation of any, not got a problem with people flying more about some of the BS rules, i fly FPV so only real way to fly legal is to fly inside, outside is so fun tho
@@pdfp24
thank you, just need to wait for the sun now
@@lievenvv
Someone didn't update there take off location for RTH 🤣
😂🤣
My guess would be interference with the radio-based positioning system they use - in the absence of this, the only thing they could do is a controlled descent as they wouldn't have any position reference to return to base.
Most systems have redundancy, they transmit over two frequencies simultaneously so if there is interference on one the drones will listen to the other.
GPS denial
Absolutely pathetic show...very few drones...why other countries can put up hundreds and now over a thousand drones and have a 3D display ...Maybe H and S controlled this event to the point it was boring...
I have been told a few times that getting swarm permissions in the UK is tough. That would certainly limit the performance.
This outfit had lost most of what they had?
£400.00 each they cost..
Nice haircut Shaun ...
Not much of it left to cut 🤣
... a drone show designed by Brexit? 🤔
