A Cargolux Boeing 747-400 freighter on a flight from Barcelona to Luxembourg was cleared to land on Luxembourg’s runway 24 in low visibility due to fog, when one of the tires from the large jumbo jetliner impacted the roof of a van parked on the runway at 12:53 local time. The airplane landed safely, the driver of the van escaped with just a shock, the van received substantial damage, the airplane suffered damage to the tire.

First preliminary results of the investigations into the incident were released on Saturday stating, that the van had been cleared to enter the runway to perform maintenance work. At that time the Cargolux Boeing had not yet begun its approach.
Hat Tip to Ian!
