Anyone lost a plane? Search begins for the owners of three Boeing 747s

All sorts of items get lost at airports, but usually they're small enough to fit inside a lost and found box.

At Malaysia's Kuala Lumpur International airport, though, they're dealing with some pretty hefty abandoned property.

Three giant Boeing 747-200F cargo planes have been parked at the airport for more than a year now - and nobody knows who they belong to.

So far, attempts to trace the current owners of the aircraft have been unsuccessful, so the airport recently placed several ads in newspapers.

In addition to a request that the planes be claimed, the advert says: "If you fail to collect the aircraft within 14 days on the date of this notice, we reserve the right to sell or otherwise dispose of the aircraft pursuant to the Civil Aviation Regulations 1996 and use the money raised to set of any expenses and debt due to us under the said Regulations."

Zainol Mohd Isa, Malaysia Airports general manager, told CNN that space was not a problem saying: "If you had an A380 we could park it."

He added: "We placed out the advertisements because we want to remove ambiguity over ownership of the planes."

"We want the owners to step forward and we want the planes to be out of our airport bay."
