What would you do with a used Rolls-Royce Olympus engine from Concorde?

If you're a bit of a plane nerd—and if you're reading this site, the odds are good that you are—a rather interesting eBay auction ended over the weekend. The auction site knows it as item number 116001533010; a less anodyne description would be a Rolls-Royce Olympus 593 turbojet engine, one of four that powered a Concorde—complete with afterburner attached.

The world's first and most successful supersonic airliner, Concorde was an ambitious and extremely expensive joint project developed by the UK and France. The initial plans started in 1956, with the first in a series of studies commissioned by the British Ministry of Supply, which set about exploring the idea of a supersonic transport plane—then, as now, the sole preserve of military jets.

A parallel effort was also underway across the Channel in France, with both countries coming up with fairly similar designs. At some point, bean counters on both sides of la manche realized that the cost of developing such an extreme aircraft was perhaps better shared than borne alone, and in 1962 the two projects—one headed by the British Aircraft Corporation, the other by Sud-Aviation combined—were merged.
