UPS Cargo Plane Sent No Distress Call Before Crash The UPS cargo plane that crashed and burned near the Birmingham, Ala., airport this morning never sent a distress signal or message to air traffic control before going down, authorities said today. The plane was nearing the runway at Birmingham-Shuttlesworth International Airport when it went down around 6:10 a.m., authorities said. It crashed about a half-mile from the airport, hitting the ground three times before skidding to a halt and bursting into flames as it hit the ground. Both the pilot and co-pilot were killed. There were no other individuals on board the plane, which erupted into flames as it crashed and its fuel caught fire near the plane's tail, according to Birmingham Mayor William Bell. Bell was briefed by National Transportation Security Board investigators this afternoon. We were told that there was no distress signal emitted from the airplane itself, and there were no calls for the airport or the control tower to assume that they were in any trouble. At this point and time that's the information that we have," Bell said. The plane had taken off from Louisville and was on final approach to Birmingham when it went down, according to authorities. Robert Sumwalt, an NTSB board member on the investigative team at the crash site, said that authorities were still working to recover the black boxes, or flight data recorder and cockpit voice recorder, from the plane. The team will collect those and other evidence to help determine the cause of the crash. "The tail section is still smoldering, still smoking and, for that reason, we have not been able to get in and get black boxes, if you will, the flight data and cockput voice recorders," he said at a news conference today. The firefighters are out there still working to do that, so we are optimistic we will be able to get in there quickly and recover those recorders. The NTSB responded to the crash site with a 26-member investigative "go team," he said. Bell said there were UPS packages and some U.S. mail on board the flight when it went down. Rescue workers were still trying to recover the bodies from the plane this afternoon, he said. Sumwalt said that he would not be able to speculate on the cause or details of the crash while the team investigated. "It appears the aircraft went through trees before it impacted at bottom of hill, where a fireball [erupted]," Sumwalt said. Then, it when up hill and came to final resting point. "This incident is very unfortunate," said UPS Airlines President Mitch Nichols, "and our thoughts and prayers are with those involved. "We place the utmost value on the safety of our employees, our customers and the public," Nichols added. We will immediately engage with the National Transportation Safety Board's investigation, and we will work exhaustively on response efforts.
