Blame congress, not engineering, the Space Shuttle we got is completely different from what NASA envisioned of just having a small, reusable space "taxi" to let people come and go from space stations, not the big, clunky, ultra expensive behemoth it ended up being.

It's a miracle that thing only blew up twice.

Not that I'm saying the Soyuz is unreliable if it is true it was just a micrometeorite.
