Its All Physics Baby! in General geocaching topics Posted November 12, 2005 I saw a cache similar to this. I like the idea of when the cache page is like.... A plane at X-Coordinates, flying a X-Bearing, at X mph drops an ammo can out of the plane. Using the information provided and some physics problem one can probably solve for where the cache is. I cannot find the link to the cache that was similar, but I liked the idea.
