Rapier, Twice Removed

What ever happened to the Rapier-turned-Pod-Racer that appeared in various behindthe scenes pictures from Star Wars? Here's the word from TheForce.net...

Remember seeing that wild looking pod from the BBC special way back when? Yeah, the one that looked like a prototype pod racer or a cloud car but with 747 engines attached to it! Observant readers have asked where this shows up in the movie, but we thought it must have been discarded. All the designs were great and creative. One gone? No problem.
