A panel weighing 4.3kg fell from a plane shortly after take-off from a Japanese airport and smashed the window of a car being driven below, news reports and the airline said yesterday.
No one was injured but aviation authorities will send safety inspectors to the western city of Osaka to investigate, said national broadcaster NHK.
The piece fell on the vehicle shortly after the KLM Royal Dutch Airlines Boeing 777 with 321 passengers on board took off from Kansai International Airport bound for Amsterdam on Saturday.
The panel damaged the car's roof and broke its rear window, NHK said.
The panel, 0.6 metres long and 1m wide, is made of composite materials and fell from the base of the right wing, Kyodo News said.
