Famed "Miracle on the Hudson" pilot Sully Sullenberger says whatever went wrong to the missing Malaysian Airlines jet likely happened quickly.

Sullenberger, who's a Danville-based airlines safety expert and investigator, speculates the problem was catastrophic and only the black box will reveal what may have happened before the plane's disappearance over the weekend. Malaysian authorities are still searching for the missing aircraft.

Sullenberger is best known for safely landing US Airways Flight 1549 in the Hudson River five years ago.
