Too funny about the hydrogen and DMHO; there's even oxygen present to feed the hydrogen fire <img src="/images/graemlins/laugh.gif" alt="" />

FYI on the Hindenburg - There was a special on PBS where a NASA scientist theorized that the Hindenburg burst into flames initially because of the flamable materials used to seal the convas exterior skin. It appears that the Zeppelin engineers used a mixture of Iron Oxide and powdered Aluminum as a sealant (and reflective coating). The proportions in the doping mixture were similar to the solid rocket boosters used on the shuttle. The hydrogen burning was secondary as opposed to the primary cause.
