Yay! I am cheering them on. I believe I found Aerocameras youtube channel, which also contains links to website, Instagram, Facebook, and Linkedin https://www.youtube.com/user/dreamsfactorysl

This appears to be the drone they're using: https://www.dji.com/mobile/t20/specs I'm not sure how to calculate the max payload, it looks like maybe 20kg.

> Standard Takeoff Weight: 42.6 kg

> Max Takeoff Weight: 47.5 kg (at sea level)

So just about 5 kg (11 lb). Medium size dogs weight trice that, plus a net, maybe the drone was modified to lift more.

Hovering time of 10-15 minutes also seems to be not that much for the rescue operation, flight and howering times with a payload will be even less.

Though website mentions thrust-to-weight ratio of 1.7 for 47.5 kg, so it can lift up to extra 33 kg. There is also a description of a spraying system with a tank of 20 l/kg, so it seems 20 kg is the actual payload capacity.

Helicopters cannot handle the potential heat. Drones have issues with payload and control. This is an Ironman situation. Someone call Yves Rossy. Seriously. This looks like an opportunity for one of the many jet/wingsuit contraptions that have appeared in recent years. Does anyone have a number for that guy spotted over LAX?

The Yves Rossy jet-powered wingsuits seem to be always air launched, i.e. they get airborne out of another aircraft. There is no ground launch. You might be thinking this kind of "jet pack" contraption: https://gravity.co/ https://www.bbc.co.uk/news/uk-england-54331994 https://www.theguardian.com/society/2020/sep/29/jet-suit-par... And I'm not saying that those are "safe" exactly, but flying them at low altitude over…

In Dubai last year one of the wingsuits demonstrated a standing takeoff, sat in a controlled hover, then transition to forward flight. If they can perfect the reverse, transition from forward flight back into hover, then Ironman will be real.

They should drop a trap with food if the dogs are still ambulatory. Avoids having to hover and make multiple trap attempts, and risk running out of power in flight. It's also easier to pick up a trap with a dog in it than trap a dog terrified of the giant buzzing thing above them. And it ensures they don't half-net a dog only to have it fall out en-route.

I'm wondering why a net vs. a cage trap? I guess it's a weight thing?

This language reminds me of the infamous Thai cave rescue. Look how public opinion turned on Elon in that instance. There are a lot of differences here, of course.

Didn't public opinion swing against Elon Musk for trying to insert himself into an already on-going rescue and then called one of the men who did rescue the kids a 'pedo-guy'? That's something I'd expect from a 13 year old on xbox live.

If the conditions got any worse, the sub would have been necessary. The kids got lucky they could use the simple method.

A trap would be the way of choice with one dog but the drone could have still problems with the extra weight

I think that they want to avoid the other dogs being alarmed and running directly into the lava crust that looks rock but is still very hot.

If they have been dropping food from drones, why have they been "eating very little"? Couldn't they just drop more food...?

Dropping more food and waiting for a better conditions for rescue is risky. The volcano is always changing and could suddenly obliterate that part with lava, or poisonous gas, or ashes. They could maybe use a trained dog in a cage as bait, but could be seen as animal cruelty.

And, well... The new Spanish law of animal cruelty is an incredible mess bordering religious stuff. The government want to force every owner of a dog or cat to castrate it by law. (Yes, trying to save tree dogs on film, wile planning forced sterilisation for all dogs and cats in Spain).

I could be wrong, but this is that they were saying on TV the last month.

If you are a dog owner and want to have your dog entire would be illegal because... think on the sad pups that could suffer if they would born (but, what is never alive can't suffer, phew!).

Sometimes I wonder if those people are real of robotic IA running wild doing laws without any real people at charge.

Vets of course would be drooling with that idea.

They have been feeding the dogs for some days now, so the dogs are used to the drones to get the food. Hopefully they will catch them effortlessly.

Yes, you could be wrong and you are. It's a law proposal, not a law in any way.

I also guess that it's a bit more complicated than that, but I won't make any assumptions before I read it myself instead of what a Spanish TV/newspaper can tell me as they are always super biased. I suggest you to do the same.

> but flying them at low altitude over hot lava would be a whole new risk

Also in every demonstration I've seen those things have been LOUD. The dogs are likely to not get on with that, so they will bolt, and there is not nearly enough time to try get them acclimatised to it.
