WASHINGTON (CNN) -- A passenger sitting at the rear of the US Airways flight forced to land in the Hudson River testified Tuesday he climbed over about a dozen rows of seats as he tried to escape through the front of the floating plane. Capt. Chesley "Sully" Sullenberger testifies in Washington about landing in New York's Hudson River. Billy Campbell is the only passenger scheduled to testify before an aviation safety panel chaired by Robert Sumwalt, vice chairman of the National Transportation Safety Board. Tuesday was the first of three days of hearings, which will try to determine the probable cause of the January 15 accident, he said.
