McGruber (1417641) writes "Boeing builds its 737 airplane fuselages in a Wichita, Kansas factory. The fuselages are then shipped on top of railroad flatcars (as shown in this photograph) to Boeing's Renton, Washington plant, where assembly is completed. Unfortunately, a train carrying two fuselages to Renton derailed approximately 18 miles east of Superior, Montana. The 737s slid down a steep embankment and ended up in the Clark Fork River. That'll buff right out."
