The National Transportation Safety Board is expected to meet in Washington this morning to consider investigators' findings on the 2004 crash of a charter jet in Colorado that killed the 14 year old son of NBC Sports executive Dick Ebersol.
The jet's pilot and flight attendant also were killed.
Federal officials are expected next week to determine the cause of that crash.
The twin-engine Canadair jet carrying Ebersol and two of his sons crashed shortly after it took off from an airport in Montrose on the morning of November Eighth, 2004.
Investigators have said they were considering whether ice on the wings contributed to the crash.
The temperature was just below freezing, with mist and flurries in the air.
