A train carrying Boeing fuselages to assembly plants in Washington state derailed in Montana, dumping the aircraft parts into a river. No one was injured, but I'm guessing someone's airplane deliveries might be late.
The video is taken by river rafters coming up on the scene.
And here's a go around at Barcelona: Russian crew forced to put in the power and abort their landing at the last moment because an Argentinian aircraft was taxiing across the runway. I don't know whether this was the result of an ATC error, or the Argentinians failed to hold short of the runway.
