Safety Board said Friday that officials will work over the next year to determine what caused the Cessna 550 Citation to crash just before 4 a.m. local time Thursday.

Daniel Williams, the former drummer for The Devil Wears Prada, was among the victims of a fatal plane crash in San Diego. The band paid tribute to the musician, writing, 'We owe you everything.'

Two people were killed in a small plane crash in Colorado on May 17. The plane left Rocky Mountain Metropolitan Airport in Broomfield at around 10 a.m. local time and crashed shortly after takeoff. Officials said the pilot was 'trying to return to the airport due to an issue' when the crash occurred.

In the dark stillness of night, a quiet, tree-lined street in a San Diego neighborhood was plunged into tragedy when a plane clipped a main power line and crashed onto the street — turning cars into fireballs and sending hundreds of residents fleeing in a haze of smoke and confusion.
