Shandong Airlines (SDA) is an airline based in the province of Shandong, China. It operates domestic trunk routes to major cities in China.
In September 2008, an SDA Airlines CRJ7 plane broke down shortly after landing in the airport of Zhengzhou, China. So the passengers were asked to get out and help push the plane to the gate.
It took the 69 passengers and 7 crew members over 2 hours to push the 20 ton plane to gate, 1000 feet away. [Source]
