I heard one son survived and is injured and one son is missing.
A witness said the impact ripped the cockpit from the fuselage, and that Charles Ebersol helped his 57-year-old father to safety through the front of the plane.
A second son, 14-year-old Edward, was missing, Denver NBC affiliate KUSA-TV reported. The station said crews searched by helicopter and on the ground, but that even "Teddy" Ebersol’s plane seat could not be found. A Montrose County Sheriff’s spokeswoman said the boy had not been located by late Sunday.
