It's interesting that you say that.

I was just thinking overnight about the following question. I will post it as a separate thread. If a small rescue drone could drop a light package to a victim ( package maybe weighting 2 pounds) , what should be in the package? There are probably a variety of answers to that question, and no perfect response. The immediate thing that occurred to me is that the package should contain an emergency transponder so the victim can be located again. Other than that ... I am open to suggestions. Two pound is not much wright, so the choices are hard.

Also, Doug's response is probably true. Crowdsourcing to random people probably isn't very effective. But if crowdsourcing was done to people living in the same region and terrain as the victim, that might produce better results.
