Aviation investigators say NBC Sports executive Dick Ebersol told them his chartered jet struggled just 20 feet into the air before it fell back to the runway and broke apart. The crash Sunday in Montrose killed Ebersol's 14-year-old son, Teddy, and two crew members.
Meantime, federal investigators have requested a report on a 2002 crash involving the same kind of jet.
A spokesman for the National Transportation Safety Board says circumstances in Montrose were similar to the earlier accident in Birmingham, England.
Investigators are trying to determine why the charter jet crashed.
Ebersol's 14-year-old son, Teddy, the pilot and a flight attendant died in the accident. The copilot is in critical but stable condition at the Denver Health Medical Center. Ebersol and his 21-year-old son, Charlie, are in a Grand Junction hospital. Ebersol's wife, actress Susan St. James, is also in Grand Junction with her husband and son.
