PONCA CITY, Okla. (AP) - For the second day, federal investigators are combing through the wreckage of a small aircraft that crashed over the weekend in northern Oklahoma, killing all five people on board.
National Transportation Safety Board spokesman Peter Knudson says NTSB investigators will wrap up the on-scene portion of their investigation on Monday. Investigators have been at the site of the crash about 90 miles (145 kilometers) north of Oklahoma City since Sunday.
The Oklahoma Highway Patrol says the plane, an Extra EA-400 corporate aircraft, was northbound from Ponca City's airport when it lost altitude and crashed about 10:45 a.m. Saturday. Troopers say the aircraft burst into flames and five people on board were killed. They have not been identified.
The victims' bodies were sent to the Oklahoma medical examiner's office for identification.
