Answer 1:
Probably the national debt!  Well, the most expensive single thing
ever made?  That's a good question.  I would tend to think along the
lines of large structures such as bridges, or high technology.
The B-2 Stealth Bomber costed about 800 million dollars each, so that's
fairly expensive.  Not sure.

Answer 2:  The Hubble Space Telescope cost about 2 billion;
Space Station Freedom is expected to cost about 20 billion,
assuming it ever gets built.
