Hi Sterling, Anne and all,

I couldn't find much on the fall rate in Sterling's link, but did a
search on the meteorite central site and came up with a lot of results
for those who want to pursue fall rates. Link below. Best!

> There are many scientifically calculated fall rates. Most assume meteorites

> A Canadian study estimated some 21,000 falls per year.
> We loose 3/4 in the oceans, leaving some 6,000 to land on dry land.
> Many of those land in remote areas away from the notice of people.
> Higher populations usually result in the notice of more falls. Light

> Of all the falls, only 0.1% or about 5 to 6 falls per year are actually
> collected. The 1933 year was an excellent year for recovery of falls.
> 17 meteorites of the potential fall total were recovered!
