Investigators are trying to figure out what led to a fatal plane crash Friday afternoon in Schuylkill County.

William Hanson, 65, of Queens, New York was killed when his glider plane went down in a heavily wooded part of Walker Township. just a short distance away from Heisler's Dairy Bar.

The Schuylkill County coroner says Hanson was the only person on board and there was no way he could have survived the crash.

"There was extensive internal trauma, pretty much most of the major bones in the body had been fractured," said Dr. David Moylan, Schuylkill County's coroner.

Hanson crashed in an area near Valley Road.

"I guess a lot of people heard like loud bangs or something because I mean it's very unusual for something like that to happen," said Shelly Heisler of Walker Township.

Heisler lives close to where the accident happened. She wasn't home at the time but her husband was.

"I was working up at the garage up there and I noticed a helicopter was circling around. Then I guess a neighbor was out and said 'A plane, a glider went down,'" said Todd Heisler.

The coroner pronounced Hanson dead at the scene just after 6:30 Friday evening.

"The best I can tell is the flight originated from a glider port in Blairstown, New Jersey," said Dr. Moylan.

But Moylan doesn't know where the pilot was headed. That's one of several things federal investigators are now trying to figure out.

"I would say to the family, this was instantaneous. This man did not suffer," said Dr. Moylan.

The Federal Aviation Administration and National Transportation Safety Board are continuing to investigate the cause of Friday's crash.

The coroner says an autopsy will be completed in the next few days.
