US Airways Capt. Chesley Sullenberger stayed calm as his aircraft glided to a water landing in the Hudson River, according to tapes released Thursday by the FAA. Sullenberger says, "We lost thrust in both engines. We're turning back towards LaGuardia." Controller Patrick Harten urgently radios two airports to clear an emergency landing. "We can't do it," Sullenberger responds, then moments later: "We're gonna be in the Hudson."
