A single-engine airplane slammed into an office building in downtown Anchorage, Alaska, and burst into flames before dawn Tuesday morning, killing the pilot, but no other casualties were immediately reported, police and fire officials said.
The plane crashed into the six-story Brady Building, which houses the Anchorage offices of the Alaska Attorney General, shortly after 6 a.m.
Debris struck an adjacent building, blowing out an electrical transformer and causing a power outage in the area, a city fire department spokeswoman said.
Because it was early in the morning, few if any people were in the building at the time, and an initial sweep of the property found no sign of anyone hurt on the ground, the official said.
The plane belonged to the Civil Air Patrol (CAP), a volunteer auxiliary of the US Air Force, but the CAP website said the pilot was not authorized to fly the plane.
The website identified the pilot as First Lt. Doug Demarest, and said the National Transportation Safety Board was investigating the crash.
Local fire officials said foul play was not suspected in the crash.
