I've just come across something very interesting regarding the long-running reports about the large FEMA plastic coffins.  There is a patent application from 1995.

You can go to http://www.scribd.com/doc/17690179/multi-functional-cremation-conta... to see the patent.

It may take several minutes for the site to download, as it appears there might be 'something' blocking fast download in order to get you frustrated and you'll move on. Be patient.  It is highly informative and verifies and validates all of the videos and reports about the massive numbers of these coffins (which can hold up to 4 bodies) that have been made, stored and distributed throughout the country.

I would imagine that there are millions of these boxes by now.
