Brilliant Intercessions footage

I've just discovered "your chance to live: Earthwatch 1972" whilst having a good scout around the Prelinger archive. Its got some brilliant footage for intercessions etc. (tsunamis, earthquakes, forest fires etc) and is public domain. Needs a good edit tho before actually using in a service! The really good stuff starts at least halfway through so be patient.
