That thing was so close to being ready; just let down by the composite tanks. The state-of-the-art in composites has advanced so much since the 80s, I'm sure if they tried again now they'd have no problem.
A let down by the NASA administration who testified to Congress that there was no point to it without the composite tanks. Even though the alternative Al-Li tanks already being designed were better by every relevant engineering metric. The X-33 could have launched but the funding was pulled.
