The design and engineering blueprints for the Millennium Falcon. I always thought the main area where Luke hung out and battled the floating orb was closer to the cockpit. In the movie, it also seemed like a much longer run from the doors to the cockpit.
Recently, my 6 year old son acquired an old Lego set from the Star Wars line – the old Millennium Falcon set from 2004. Problem was that it was acquired from a school thrift sale, meaning the set was used, it was in a brown box and not in the original packaging, and the instructions were nowhere to be found. We (OK, my son) decided that we wanted to start building it today but with no instructions, this would prove to be quite the challenge. With about 5 minutes worth of searching, with relative ease we were able to find the instructions booklet online. Click, download the PDF, and we’re in business. Yet another reason why the Internet rocks.
