SHANGHAI, Nov 28 (Reuters) - A Zimbabwean-registered cargo plane crashed on take-off at a Shanghai airport on Saturday, injuring four people on board, state media said.

Thick smoke rose above Pudong airport and firemen were at the scene, Xinhua said.
The crash happened early in the morning as the plane was taking off. The plane skidded and set fire to a nearby storage facility, China's national broadcaster CCTV reported.
