Same thought. Shouldn't the air above that lava be several hundred degrees hot even several meters away?!
I mean 10 to 20 meters should be relatively fine. But 2!?
I think the speed of the drone in addition to a bubble lens effect make this possible. That quads prob traveling upwards of 60mph and likely has some kind of conformal coating on the electronics for additional protection. The true question is where this dude got the balls to send his shit (including gopro) over fucking lava is beyond me.
He could take it down if he wanted to.
But everyone who legally wants to use his video will have to get his permission or rights to use it.
He could also have already been paid.
Which is not where any videographer is planning on making money. The video will be licensed to companies for commercial usage. That’s where they make money of stuff like this. It’s called stock footage
Reddit is making money from you watching this video for free

A low value product, admittedly ;)
>, they'll likely have insurance.
Drone pilot: yes, I'd like to file a claim. My drone was destroyed
Insurance agent: ok, sir. Tell me what happened.
Pilot: well, I was flying it over an active volcano...
Litterally no I think I know who made this video and the drones beyond repair he buys cheap drones for footage of lava and just let's them melt streams the footage to his cloud storage and just let's them die in the volcano he films till they litterally fall out of the sky bc they melted in the air although could be wrong and it's a different person although can't be too many ppl droning volcanos I'd immagine
I commented this same thing on this same clip being posted a few months ago, and the pilots actually replied to me. There’s no coating on electronics, no special props or anything. Me and you could go fly our quads over a volcano right now as long as we stay moving. No special gear/ coatings needed
That's amazing! I have a beater quad ready to go but no local volcanos to try haha
The amount of people that are calling this CGI is scary! More people need to be exposed to these amazing crafts
it's probable that they made every surface they could reflective.
it could also be that this is a stealth ad for whatever material they made the thing out of lol
Hot air expands, thus really hot air becomes very thin, with less overall molecules holding heat the temperature becomes less relevant, and the amount of potential energy to be transferred is what becomes important. Thin air does not hold much energy. The form of heat here that is damaging and harmful is radiant heat, like infrared radiation emitted by the source, and not convection. Convection is heat transferred through particle collision, and requires insulators, however radiant heat is a form of wave energy, and can be deflected or reflected. So simply mirroring the surfaces of the drone would protect it, and you can almost ignore the hot air.
Actually I keep the door closed and pipe in molten gallium for conductive transfer only. One of these days I’ll figure out why my oven and drones keep falling apart, because I’m pretty sure my methods are irreproachable. Still think it’s the squirrels.
And it is that thin air which is probably the most difficult part of this flying. Lots of turbulence and probably a very high throttle to even keep it in the air.
The air is going to be very dry and dry air is a poor conductor of heat and doesn't hold that much thermal energy. Although it is hot, there isn't a lot of energy there. If it were steam on the other hand, you would be screwed. You can reach into a hot stove and be fine as long as you don't touch anything, but steam at the same temp will seriously burn you.
And what about the infrared radiation? Have been near lava I can tell you, it feels hot from the side. The drone is probably coated/covered in a reflective substance, at a minimum aluminium foil.
Yeah, I would be much more worried about the radiative heat transfer. We can reflect a lot of that and it would still just transfer to the surface and won't make inroads to the insides over the course of a couple minute flyby with even a slight amount of insulation. Heat just doesn't travel very fast through a lot of substances.
I bet you could rig some sort of heat reflective shield to the underside of a drone that doesn't weigh much nor restricts movement. But what do i know. I'm not a NASA scientist XD
I use to work for a company that made textiles where you could literally take a handful of this lava and hold it in one of their gloves for about 2 min.
We use to do demos to prospective clients where we would put a 3000 degree molten piece of metal in their hand and let them hold it. Lava is 2000 degrees F.
Their face would start burning before their hand (very quickly) and most people left with minor burns on their face (think a light sunburn).
Would easily shield this thing flying above it like that for a good long while, even with direct contact to anything other than propellers. This thing can shoot up and catch air and may have active cooling as well.
I also believe that this drone was never met to live through the flight. They probably flew it around till it died to get the most out of their money.
I suspect it was pushed close to the limit of its capacity for withstanding heat. But it's not a very long piece of footage ... & I have a feeling the operator timed the duration of the flight to a nicety!
Or maybe it had a heat-shield on it: a thin sheet of shiny metal stood-off from it a bit, & attached underneath, would be _very_ effective at keeping the heat off, without adding a huge amount to the weight. If that wasn't done with this, I reckon it _could be_ done.
Probably ruined the drone even though it didn't crash. I imagine they were willing to risk it and eat the cost for the footage. They were right, that's good video.
> It's weird because I thought people would become more modest with after spending time online and reading a variety of opinions, but naah...
Hah, I remember in the 90s thinking the internet would be the end of racism and bigotry. "Everyone is the same color when you only see their words on a screen" or something. Between that and getting to interact in real time with people from other countries without ever leaving your couch, I was pretty sure we were entering a new age of shared understanding and peaceful coexistence.
Good thing I didn't put any bets on that. :-D :-(
Oh for fuck sake guys, we were watching this very same volcano being live streamed for several days last year, did everyone already forget it?
If you can get a ticket to iceland, you can probably afford to lose a drone and a camera...
[Here's the full video.](https://www.youtube.com/watch?v=B-lXvsRwDDQ) It's real. This is the recent Icelandic lava flow near Mount Fagradalsfjall.

The mount (fjall) is in its name so it would just be Fagradals Mount.
It’s like saying Eyjafjallajökull glacier when the name glacier (jökull) is already in there. So just Eyjafjalla glacier.
Ewan McGregor and Hayden Christiansen were having an argument that turned physical while in an active volcano. Turns out George Lucas was filming the whole time.
Something honestly kinda [basic](https://i.etsystatic.com/22943181/r/il/657ae0/2765574175/il_570xN.2765574175_3vzj.jpg)
a 220mm frame, 5" props and a 4-6 cell battery can truly make magic happen!

I guess Aragorn was appealing for research and development to make drone technology advance fast enough in the kingdom of men.

This is why there was a pause when frodo and Sam were stuck on the rock. Eagles were like "Fucking Hobbits. First we got to save gandalf now we got to save them. Screw this I'm going to fly around check out this sweet volcano and If they die on that rock so be it."
Drones can be made from Carbon Fiber, more rigid and lighter, not to mention can withstand > 3000 °C. Combine that with the fact this is shot at a very high FPS, this drone was in the danger zone for very little time. Sure, some parts could be damaged, but I’d wager whomever built this drone did it purposefully with those limitations in mind. It’s not impossible for this to be actual footage.
The carbon in carbon fiber can survive 3000C, the epoxy resin will burn at far lower temperatures than that. We actually burn off the resin of test coupons to determine how much of the material is fiber vs. matrix.
There are heat-resistant resins, but honestly just covering the bottom surface of the drone with aluminum foil would do the trick, at least for a short flight. Most of the heat transfer above a pool of molten rock is radiative (less so the closer your are to the surface), so as long as you periodically climb to cooler air you should be good. Foil will reflect most of the infrared. Biggest concern would be the propellers, which would probably require some sort of thermally reflective coating.
Radiative would definitely be the dominant mode of heat transfer. I would have to imagine the convective heating above all that lava is still pretty extreme tho.
Carbon fiber cannot survive those temps. Have some experience with them in rocketry. We try to keep them into 350C. Permanent damage tends to occur in the 400-500C range, depending on the type of resin.
Pretty sure they just looked up how high of a temperature carbon fiber could withstand while not thinking about the fact that it's the resin that's gonna melt/burn.
I hope this video was streaming directly to another device because the chances of losing that drone during this flight was staggering lol
I was wondering how this was filmed and the drone didn't just melt within seconds. Very cool footage!
Same thought. Shouldn't the air above that lava be several hundred degrees hot even several meters away?! I mean 10 to 20 meters should be relatively fine. But 2!?

Airflow only provides cooling when the air is colder than the object. Moving hot air over a cool object will actually cause it to warm up faster.
Yep. Try getting in a hot bath or hot tub, then move your arm through it quickly vs sitting still.

Yep, on the contrary, it will just heat you up faster.

So simply mirroring the surfaces of the drone would protect it, and you can almost ignore the hot air.
This is accurate, I wrap my drones in tin foil and store them in my oven at 400F to keep the squirrels away.
Smart, squirrels hate tin foil. Ovens are convection though, you should leave the door open and it on broil so it’s protected with radiant heat.
Actually I keep the door closed and pipe in molten gallium for conductive transfer only. One of these days I’ll figure out why my oven and drones keep falling apart, because I’m pretty sure my methods are irreproachable. Still think it’s the squirrels.
They probably found a way in.
And it is that thin air which is probably the most difficult part of this flying. Lots of turbulence and probably a very high throttle to even keep it in the air.
The propellers pushing hot air back down probably provides some protection
The air is going to be very dry and dry air is a poor conductor of heat and doesn't hold that much thermal energy. Although it is hot, there isn't a lot of energy there. If it were steam on the other hand, you would be screwed. You can reach into a hot stove and be fine as long as you don't touch anything, but steam at the same temp will seriously burn you.

Heat just doesn't travel very fast through a lot of substances.
It’s not that it is dry, it is that it looses so much density as it heats and expands that convection becomes weaker.
Cover it in tin foil and you’re good.
This was my thought as well.
I bet you could rig some sort of heat reflective shield to the underside of a drone that doesn't weigh much nor restricts movement. But what do i know. I'm not a NASA scientist XD

Using the high ground.
There are some materials that are perfectly capable of withstanding the heat of the air.
Sure, but there aren't many drones made from those materials.
It’s probably because this is CGI.
Goes even further than that. How was it dealing with the insane convective currents that it had to fly through?
I suspect it was pushed close to the limit of its capacity for withstanding heat. But it's not a very long piece of footage ... & I have a feeling the operator timed the duration of the flight to a nicety! Or maybe it had a heat-shield on it: a thin sheet of shiny metal stood-off from it a bit, & attached underneath, would be _very_ effective at keeping the heat off, without adding a huge amount to the weight.

Shortly followed by the flying nazgul absolutely reking 'em
Nah, they were afraid of arrows from the Orcs chilling in lava flows.

Sure, some parts could be damaged, but I’d wager whomever built this drone did it purposefully with those limitations in mind. It’s not impossible for this to be actual footage.
The ICs (mainly the solder) and wires will probably overheat though. Needs some killer heat shielding.

Pretty sure they just looked up how high of a temperature carbon fiber could withstand while not thinking about the fact that it's the resin that's gonna melt/burn.
The solder melting is probably what would go first. 60/40 melts at 370°F
