There are a few unusually large items lying at the lost and found counter of Kuala Lumpur International Airport.

Malaysia Airports placed an advertisement on Monday in the nation's best-selling English daily asking for the owner of three Boeing 747-200F planes to come and collect them. The planes are parked at three separate bays at KLIA in Sepang, outside the Malaysian capital, the Star newspaper ad showed.

"If you fail to collect the aircraft within 14 days of 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 off any expenses and debt due to us under the said regulations," the notice read.
