I don't miss it. Was it inspiring? Yes. Was it practical? No. 1 billion dollars per launch and it didn't even get past LEO. Not to mention the stupid, dangerous decision to use solid rockets.

It used liquid boosters, which were far safer than solid fuel. Also, check out this: Shuttle's Payload to LEO:24,400 kg Buran/Energia payload to LEO: 100,000 kg
