A german tabloid just posted a funny picture about a parked A340 that tried to sneak out of FRA. Regardless of the correctly placed brake blocks, the unmanned rascal managed to set itself free and decided to have a little sight seeing until a fence stopped its adventure.
LH PR was confirming that the icy parking position and the nasty wind may caused that incident. Minor damage was reported and - naturally - that a/c is send to the penalty box for a close inspection before returning to active duty.
Have you got a link? I'd like to see this one!
