That jacket seems already ice frozen to me
Nice work anyway! I like the way this guys sticks with his idea and existing materials and make it work no matter how many people tell him there are more dedicated aerial vehicles for this job or whatever else. Hat down and fingers crossed in real situations.
I wanted to use a real guy who fell through the ice but couldn't find any volunteers. /s
I still firmly believe that a matrice would be a much better delivery vehicle but a mavic can be a viable alternative.
In fact, the size and portability of mavic might make it a better option depending on the scenario.
Mavic isn't rated to fly below freezing but from my experience people tend to fall through the ice when the air temperatures are warmer and the ice is beginning to thaw.
Also, many people have flown mavic in extremely cold temperatures with great success.
I am pretty sure that cold air is more dense and should make it easier to generate lift.
Im not advocating for mavic to be the only solution for ice rescue. Often, there are a limited number of rescue suits and many responders on scene. In most scenarios, the rescue team should absolutely continue their efforts with traditional methods while alternate methods, like a drone, are utilized.
It's always great to have plan b, and c when time is of the essence.
