OFF topic - seeing meteors and finding meteorites, a short discussion

>From the thread it appears the inquires on using all sky cameras and
coordinating the path of a big fireball will help locate a fresh
meteorite fall.

It is interesting that there has been no discussion of doing the actual
field work to find the fall.

Even if there is a meteorite impact on the ground, in an isolated area,
the chance of a quick find is not high. Two fresh examples would include
the  (2007) screamer in Alberta and the Pennsylvania fall in the Sproul
Forest in 2001. The Sproul  was estimated to be between  30 to 90 tons.
Yet still no one has stepped forward with a sample. And the terrain in
NE Pennsylvania is difficult.

We have been working on a "simple" problem for the past few years of
finding meteorites in coal seams. We have one sample and still the
analysis is inclusive.

I guess it has to be remembered that seeing a bright fireball heading
through the atmosphere, either visually or with automated eyes,  does
not mean it impacted the surface.
