A plane flying over northern Colorado dropped debris in Broomfield after experiencing engine trouble but landed safely at Denver International Airport Saturday, officials said.
Much of the debris landed in Commons Park and in the Northmoor and Red Leaf neighborhoods of Broomfield, which is about 20 miles north of downtown Denver.

A large circular piece of the plane fell next to a house in Broomfield, Colorad.
