Yes, it would have to be a first recovery to eliminate any dispute, I think. I am thinking of a situation where the fireball was witnessed and well documented, but no locals saw, heard, nor found any stones. I suppose if the triangulation hunter came along and defined the search area fairly narrowly to begin with, then recruiting locals to help search that area wouldn't necessarily disqualify a find. Basically, I'm wondering what's the first find that would probably not have occurred without accurate triangulation calculations?

How do you count a situation where a fireball is triangulated the hunter arrives at the strewn field and offers an incentive to them. The question needs to be further limited to the first recovery, I think? But what of the case where a local finds one and the triangulation hunter comes and without input finds a fragment at a later date.

And granted, even with all of this technology, strewn fields are often difficult to pinpoint today. But it's hard to believe that it took over 150 years after general scientific acceptance of the fireball/meteorite connection for somebody to start accurately tracking these suckers.
