yep just think how much stuff is out there, a few years back I was spotting and saw bits of metal from about 800 yards away lots of reflections, thought it was part of a plain crash or something big .
Turns out it was a survival blanket all tore up and strewn around a 10 yd area. looked around some more and found a military style vest "tore up good" but it contained three knives and a compass .

hear is a pic of the vest LOL
