This happened to me once. I lost the pattern, yarn and needles on a plane. Happened about 2 years ago, but I was just thinking about it yesterday for some reason. I was wondering if whoever found the stuff (I called the airline several times and it wasn't turned in) actually made the project ... if they did, I bet they ran into trouble! When I got home, I learned that there was a bunch of errata for the pattern, which explains the trouble I had been having on the plane.
So, I consider that situation resolved. I'm glad you got yours resolved too!
