The craft was designed to sink and will not be recovered.

And why wouldn't they want to look at the thing after this flight?

I gotta beleive that it was tracked to a relatively small area - and why couldn't it have had a transponder?

Or maybe after 10 secs at Mach 10 it melted and is now a blob of titanium?
