As I mentioned to Steven in comments to the previous post about the pending satellite shoot-em-up, I don’t buy the argument that the hydrazine in the fuel tanks is a real threat. The Cassini-Huygens probe carried plutonium aboard as a fuel source and I recall the crazies all worried it would somehow contaminate the earth if it crashed or failed on liftoff; why would hydrazine be such a big deal? A satellite coming uncontrolled down from space has only 30% chance of hitting land to begin with, and the actual populated areas of Earth where you might conceivably land on someone (ie, dense urban areas, not suburbs, farmland, desert, jungle, etc) are an even smaller target. The risk has to be infinitesimal.
So i am not surprised at all to see that there might be an ulterior motive – to show the Chinese we can.
