Obituaries say both McFawn and Jenkins were married fathers of two.

Parsons’ obituary describes him as “the best husband ever,” and says the helicopter flight instructor served three tours in Iraq for the U.S. Marine Corps.

All three were killed Thursday when the helicopter they were in collided with an airplane near the Frederick Municipal Airport. The cause is under investigation.
