Investigators are trying to establish why a landing Cargolux Boeing 747-400F struck a vehicle as it touched down yesterday at the freight carrier's Luxembourg base.
The incident, which occurred at 12:53, occurred on runway 24 as the jet, operating as flight CV7933, was arriving from Barcelona.
Cargolux says that the aircraft - identified as LX-OCV, serial number 29731 - was landing in low-visibility conditions, and hit an empty maintenance van with its main-gear tyres.
"There was no-one in the van, and no-one was injured," says a spokesman for the carrier. "The aircraft made a safe landing and was checked."
There appears to be no structural damage to the 747, he adds.
Meteorological data from Luxembourg Findel Airport at the time confirms fog, with visibility of 100m and a runway visual range of 350m.
Investigators have opened an inquiry into the incident, says Luxembourg's transport ministry, which states that the van had been parked on the runway to carry out repairs to lighting.
