GREENE TOWNSHIP -- We are learning more about a deadly helicopter crash Sunday night in Pike County.
Investigators were on the scene all day Monday in a remote wooded area near Skytop Lodge.
Officials say the chopper took off Sunday morning headed to a small private airport not far from the crash site off Route 390 north of Canadensis.
The pilot never reached his destination and crashed in the woods.
Investigators with the National Transportation Safety Board, FAA, and Pike County EMA were at the wreckage Monday looking for what caused the chopper to crash about 30 to 40 minutes after takeoff.
The Pike County coroner is not expected to release the pilot's name until Tuesday.
Investigators could not say why the helicopter wasn't considered missing until around 9 p.m. Sunday when the search started in the area of Skytop Lodge in Monroe County.
Emergency crews were able to use the pilot's cell phone signal to locate the crash scene.
"The helicopter has been fragmented into several pieces. Whether or not it's upside down is something we're still looking at. It's not very clear at the moment. But we've just begun. We've just gotten myself and our experts here. We've just started, so I wish I had more information about the details. We just don't have it yet," said NTSB official Doug Brazy.
Officials say the helicopter was headed to Mountain Bay Air Park located in a private development several miles north of the wreckage in the Greentown area.
Crews are expected to remove what's left of the helicopter Tuesday afternoon, but still have lots of work to do to determine what caused the deadly crash.
Anyone who witnessed the crash should call the NTSB.
