Denver ? The body of Edward “Teddy” Ebersol, the 14-year-old son of NBC Sports Chairman Dick Ebersol, was recovered from the wreckage of a charter plane Monday evening in Montrose, Colo., authorities reported, while the television executive and another son were recovering from moderate injuries suffered in the accident Sunday morning.

Sheriff’s deputies searched for the boy all day Sunday and most of Monday before his body was found under the shattered fuselage of the CL-601 Challenger jet that exploded into flames just off the runway of Montrose’s small airport.

“We recovered a body that matches the description of Teddy Ebersol,” Montrose County Coroner Mark Young told reporters Monday night. “It was under the aircraft. Out of respect for the family, I’m not going to discuss the condition.”

Pilot Luis Espaillat and co-pilot Warren Richardson III also were killed in the crash. A third crew member was in “very critical condition” in the burn ward of a Denver hospital, Young said.

Witnesses told reporters that Charles Ebersol, 21, stumbled away from the plane and then walked back into the wreckage to lead his father to safety.

Dick Ebersol, 57, who oversaw the network’s coverage of the Olympics, suffered broken ribs, a broken sternum and fluid in his lungs, according to an NBC source.

Charles Ebersol, a student at the University of Notre Dame, broke his hand and suffers from a sore back, the NBC official said. The source, who spoke on the condition of anonymity because the network did not release an official statement, confirmed that Dick Ebersol was rescued by his son.

National Transportation Safety Board investigators, delayed by the heavy snow that swept southwestern Colorado on Sunday and Monday, began their study of the accident late Monday.

NBC released a statement saying, “Dick Ebersol and his son Charlie are both hospitalized in stable condition and are expected to make a full recovery.”

Witnesses offered conflicting versions of what happened. One said the plane took off in a snowstorm, crashed to the ground and burst into flames. Another witness reported seeing the plane skid sideways along the runway, suggesting it might have been blown over by gusting winds before takeoff. Photos taken by witnesses show the shattered plane, amid dense flames, a few dozen feet from the end of the runway.

An FAA spokesman said that, because of the poor weather, the pilot of the Ebersol charter requested assistance from air traffic control before takeoff to ensure the plane would be clear of any traffic in the air. The FAA said it could not confirm when the controller in Denver granted the request.

A spokesman for the NTSB said the pilot declined an offer to have the plane’s wings de-iced before takeoff. Investigators recovered the plane’s cockpit recorder Monday and said they would study it to learn whether ice on the wings was a factor in the crash.

Officials investigate the wreckage of a jet at Montrose Regional Airport in Montrose, Colo. The body of the 14-year-old son of NBC Sports chief Dick Ebersol was recovered Monday after a fiery jet crash Sunday that killed two crewmen. Ebersol, his son Charles and a third crew member survived the crash.
