Wichita ? Authorities have removed the bodies of three victims from the Wichita flight training facility damaged in Thursday’s small plane crash, as well as the cockpit voice recorder.

Wichita Fire Marshal Brad Crisp said the bodies of the people trapped inside a simulator in the building were pulled from the rubble about 9:30 p.m. Friday, the Wichita Eagle reported. Their names have not been released.

“We had been working on the building for the … afternoon and throughout the evening,” he said.

The Flight Safety International Learning Center at Wichita Mid-Continent Airport was damaged when the twin-engine Beechcraft King Air 200 crashed into the top of the building shortly after takeoff Thursday. Four people died, and five were injured.

Crisp said the body of pilot Mark Goldstein, 53, will probably not be removed from the roof of the building until Saturday.

National Transportation Safety Board spokesman Peter Knudson also said the cockpit voice recorder was removed Friday evening by lowering someone in a harness into the rubble. It is not known whether the flight data recorder survived the crash because it was not in a crash-hardened black box.

“We didn’t want to wait until the building was safe to go into,” Knudson told the newspaper. “We wanted to get that information as quickly as possible.”

Federal investigators hope to begin recovering evidence inside the building Saturday.
