Maby the hurricane force winds will blow some of it away, along with the trees.

A lot of folks don't think about overpressure effects with nuclear blast, or in this case a big hunk of iron landing close to you. As little a third of one atmosphere over standard pressure will shatter windows. THe numbers are small, but the effects are large. Cool program. I tried it out on several sized objects, distances, and densities. There are a couple of nuclear blast effect computers out there on the net too that I've played around with in the past.
