I don't understand the nervousness of some people about the satellite that landed in the early hours of this morning and whose whereabouts are currently unknown. The astronomer I saw on Channel 4 News last night was at pains to point out the improbability of it hitting land, let alone inhabited areas or people.
I'd be quite excited if a bit of it landed in the garden. And if you could keep it quiet from NASA, what a souvenir to have. Even if it clipped off a few roof tiles, it'd make for an interesting call to the insurance company (although they've probably got a space exemption clause).
