The Plane That Wouldn’t Talk

"February 6, 1996 — A group of German tourists in the Dominican Republic is waiting impatiently to board their flight to Frankfurt. Mechanical problems have grounded their plane – and the airline is forced to substitute the original aircraft with a Boeing 757 owned by Birgenair. This plane has been sitting idle on the tarmac for almost three weeks. After hours of preparation, the plane and the crew are finally ready to take off.As the plane is accelerating for take-off, the flight’s Captain notices a problem with his airspeed indicator, it doesn’t match his First Officer’s gauge. In spite of the conflicting readings, the crew lifts off, and engage the auto pilot for the climb over the Atlantic Ocean. Within moments, the plane’s computer begins bombarding the cockpit with confusing alarms. The first indicates that the plane is traveling far too fast. But when the Captain reduces power slightly, he hears a warning that he’s suddenly flying too slowly. Then the cockpit fills with the sound of the most distressing alarm known to flight crews – the stick-shaker alert. The alarm warns the crew that the plane is moving so slowly, that it’s about to stall. Is the plane traveling too fast or too slow? The bewildered Captain doesn’t know which warnings to trust. The plane begins falling from sky, losing altitude and spinning wildly out of control. The crew never regains control of the plane, and less than five minutes after takeoff, it slams into the Atlantic Ocean. All 189 people on board are killed.When investigators recover the plane’s black boxes from the ocean, they learn that the crew took off with a faulty airspeed indicator, and then faced a baffling sequence of conflicting warnings from the plane’s computer. Investigators now confront a new mystery: How could the failure of one single instrument – the airspeed indicator – cause the crash of one of the world’s most sophisticated jetliners?Investigators turn their focus to the device that feeds information to the airspeed indicator – the pitot tube. They eventually determine that because these tubes had not been properly protected during the aircraft’s three-weeks on the ground, local insects had built nests in the tubes, and blocked them. That’s what caused the Captain’s airspeed indictor to malfunction. Investigators also discover that the same blocked pitot tube that fed the Captain’s airspeed indicator, also fed information the Auto Pilot. The plane was never traveling too fast, the auto pilot was getting faulty readings. The Captain’s decision to slow the plane down caused the jet to stall. But because he was getting so many conflicting warnings, he was never able to understand the problem, and take the necessary steps to recover. As a result of the crash, Boeing changed the potentially confusing alarms on their 700 series of airplanes. Boeing also made it easier for pilots to recognize that the auto pilot was getting faulty airspeed readings, and correct the problem in the flight. The crash of Birgenair Flight 301 also led aviation authorities to require that all commercial pilots undergo simulator training for a blocked pitot tube situation. "

Fatal Distraction

"December 29, 1972 — Eastern Airlines Flight 401 is preparing to land in Miami. 163 passengers are on board the sophisticated new L-1011 jet. When the crew try to lower their landing gear, only two of three indicator lights turn green. The crew can’t be sure their landing gear is locked. Without the confirmation, it would be dangerous to land. Captain Robert Loft decides to circle away from the airport and trouble-shoot the problem. The auto-pilot is programmed to keep the plane circling at 2,000 feet. Freed from the task of flying, all three crew members focus their attention on the faulty indicator. Co-Pilot Bert Stockstill works on removing the assembly to check the bulb. Second Officer Don Repo is sent to an area below the cockpit where he should be able to see if the landing gear is locked.But in the Miami Tower, the controller notices something unusual – Flight 401 is no longer flying at 2,000 feet, it’s down to 900. He radios the crew but it’s too late to pull up. The jet crashes into a remote part of the Florida Everglades. 101 people die, but incredibly 77 survive. Many are badly wounded. Jet fuel burns the skin. Alligators lurk nearby. It takes almost an hour for the Coast Guard to find the remote crash site and begin ferrying survivors to nearby hospitals.This is the first-ever crash of a jumbo jet and, at the time, the largest death toll in US civil aviation history. Investigators need to figure out why this sophisticated jet, fell from the sky without anyone in the cockpit noticing. They examine the engines for signs of failure, but find none. They recover the plane’s Auto Pilot computer and test it on another plane. There’s nothing wrong with it. Only when they listen to the Cockpit Voice Recorder do they discover that the crew was so obsessed with a light bulb, that they didn’t hear the warning that their plane was dropping. The discover that Captain Loft unintentionally disengaged the auto-pilot when he accidentally nudged his control column while turning to talk to his Second Officer. Investigators ultimately blame the accident on pilot error. The crew was so focused on the light-bulb that they didn’t look at their instruments, and didn’t notice that the plane was falling. Following the crash pilots are warned that a slight nudge of the control column can disengage their auto-pilot. But there’s a much more lasting legacy to this accident. Until this disaster investigators had never had to consider that the dynamic inside a cockpit could cause a crash. This accident changed that and forced investigators to examine human relations when considering the cause of a crash. Italso led to a whole new area of study, Crew Resource Management. As a result of this accident, pilots would be taught, not just how to fly planes, but how to convey instructions, and delegate responsibility in the cockpit. Flight 401 is taught to this day as an example of poor Cockpit Resource Management."

Phantom Strike

"September 29, 2006 — Fresh off the factory floor in Southern Brazil, a sleek $25 million Legacy business jet is being delivered to its new owner in New York. An hour into the flight the plane is powering through the skies over the Amazon Rain Forest. Suddenly a violent jolt sends shock waves through the plane. Passengers look out the window and are horrified to see that part of the plane’s wing has been sheared off. The jet has become hard to control, and the damage to the wing is getting worse. The crew must land. Below them, a dense jungle stretches as far as the eye can see. Luckily the crew spots an Army base with a runway long enough for their plane. But with the damage to their wing they know it could be a rough landing. They come in fast, but manage to bring the plane to a stop before the end of the runway. That’s when a whole new problem develops. The passengers and crew are detained and interrogated by police. Another plane, a Boeing 737 with 154 people on board has crashed nearby. Everyone on board GOL Flight 1907 was killed. Investigators suspect that events on the Legacy and the crash of the GOL flight are related, but how? Investigators studying the crash of the GOL plane make a telling discovery. They find paint on the GOL’s wing that matches the paint on the Legacy jet. It’s clear that the two planes collided high above the Amazon. How had two planes under the authority of Brazilian Air Traffic Control ended up on a collision course? The investigation would uncover a string of technological and human errors that would lead to criminal charges and an unprecedented crisis in Brazilian aviation.Investigators learn that both planes were assigned the same altitude by air traffic controllers at opposite ends of the country. The small jet was supposed to drop to 36,000 feet part way through its flight. If it had, it would not have collided with the 737. But for some reason air traffic controllers never gave the Legacy the crucial order to descend. Instead, the plane stayed on its collision course. Investigators uncover a dangerous flaw in Brazil’s computerized air traffic control system. The computer led controllers to believe that the Legacy was flying 1000 feet lower than it actually was. Both aircraft were equipped with a safety feature designed to prevent mid-air collisions. The system relies on signals from an airplane’s transponder. But the Legacy jet’s transponder was mysteriously silent for more than fifty minutes leading up to the crash. This meant there was no system to warn either crew that a plane was closing in on them. The investigation ultimately reveals that Brazilian air traffic controllers are overworked and poorly trained. Two of the controllers on duty that day are charged with manslaughter. The tragedy of GOL Flight 1907 leads a major overhaul of Brazil’s air traffic control system"
