Terry Carlson of Kensington and Jason Williams of Silver Spring were killed after the plane Carlson was piloting crashed, according to WTAE. Carlson's son, Erik Carlson, was flown to a nearby hospital with severe burns, WTAE reports. 

Investigators tell WTAE that one of the doors of their Beechcraft BE36 aircraft became unhinged shortly after takeoff and hit the plane's wing. 

The crash happened about half a mile from the Nemacolin Woodlands Resort in Farmington, Penn., according to the FAA. 

The National Transit Safety Board is investigating the accident.
