Ahahahaa... try to get funding for that.. -sigh- If you're trying to protect a city from an ongoing eruption you might have a chance. So, the $1k toy is actually being trialed around the world, just with more complex instrumentation. You can get closer without risking anyone, and you can make much more frequent measurements since it's so much cheaper. The biggest problem is the wind and turbulence (since volcanoes are mountains with a heat source, and almost nobody in the field is an experienced drone pilot).
