The problem wasn't a "chemical", actually. The real problem was that nobody really appreciated that almost *any* organic material soaked in LOX is a powerful explosive. The LOX plumbing used gaskets made of a chemically treated form of leather. They finally figured this out when they had a gasket explode while the plane containing it was still on the ground. Even in rockets, liquid hydrogen gets all the bad press but liquid oxygen is much more dangerous. -- "[Some people] positively *wish* to | Henry Spencer @ U of Toronto Zoology believe ill of the modern world."-R.Peto| henry@zoo.toronto.edu utzoo!henry
