Plane Crashed into a Hangar Prompting Fears of Fuel Leak

 A passenger jet undergoing an engine test at a Californian airport has smashed into a hangar.
The crash sparked fears of a fuel leak and led to the evacuation of other nearby structures and buildings.
Three mechanics were on board servicing the plane at the time but officials said no-one was injured.
The Bombardier Canadair regional jet, which can carry up to 50 passengers, was on a ramp when it suddenly started rolling and struck the Encore Jet Centre at Chino Airport.
It apparently went over the rubber stops put in place to prevent the plane from moving, said Robin Dill, a retired commercial airline pilot who heard the crash and talked to witnesses.
Ian Gregor, spokesman for the Federal Aviation Administration, said in a statement: "There were three mechanics on the plane, but none was injured.
"The plane was not intended for flight."
Firefighters attended the crash, and at least four ambulances went to the scene.
A report of a fuel leak proved to be incorrect.
