The external tank destined for display at the California Science Center is
ET-94, the last flight-qualified external tank in existence. This lightweight
tank (LWT) — donated to the Science Center by NASA — was ordered to support
science missions for space shuttle Columbia.

- dylan604 3y agoThere are lots of "stories" like this from space programs. The ESA "lost" the fuel tanks for their last Vega launch because they were just sitting around for so long they got crushed down into scrap metal because they were not entered into their asset management software.[0] [0] https://europeanspaceflight.com/the-case-of-the-missing-vega-avum-propellant-tanks/ https://europeanspaceflight.com/the-case-of-the-missing-vega...
