“It’ s extremely difficult to get there, ” said Ademir Ribeiro, a foreman on the nearby Jarina ranch, the centre for rescue operations. 737 Crashed, Legacy made emergency landing A Embraer Legacy 600 owned by ExcelAire, a charter company based in Long Island, New York clipped the Boeing 737-800 SFP. The Legacy made an emergency landing at Cachimbo air force base with five passengers and two crew on board, none of whom were hurt. The Boeing plunged nose first into the rainforest and disintegrated. “ Neither of the pilots can understand how a 737 could have hit us without them seeing it, ” said Joe Sharkey, a journalist for the New York Times, in an email to his wife. Mr. Zuanazzi says it ’ s possible as they were traveling at hundreds of miles an hour. “ They said they didn ’ t see anything. But this is absolutely normal. …In these conditions, you can only see a shadow and a noise, ” said Zuanazzi. Questions over collision avoidance system Investigators are trying to determine why two new aircraft equipped with the latest anti-collision technology could have collided. The Brazilian air force says that both planes were equipped with a Traffic Collision Avoidance System (TCAS) which sounds an alarm when planes get too close. “ It locks on the other plane ’ s transponders and tells the pilot whether to go up or down, ” John Hansman, aeronautics professor at the Massachusetts Institute of Technology, said by telephone. “ The 737 should have been warned to take evasive action. ” Hansman said that in air traffic in Brazil is complicated in some parts and vast areas are not covered by radar especially over the ocean on the Amazon Rainforest. Pilots often propose a route and at certain points check with controllers who verify the plane ’ s location, altitude and bearing. “ Apparently that process broke down somehow, ” Hansman said. “ When you get to the jungles of Brazil, you have people going in all directions. ” Blackboxes recovered The cockpit voice recorder and the digital flight data recorder of both planes have been recovered. The blackbox of the Legacy was taken to Embraer's headquarters at Sao Jose dos Campos, Sao Paulo. Brazil ’ s Civil Aviation Agency said the cause of the crash was impossible to say until the Boeing 737's two recorders, found by search teams, were examined. “ It might indicate they were flying an altitude they weren ’ t cleared to fly, ” Mr. Oderman said. Bill Waldock, aviation safety professor at Embry-Riddle Aeronautical University in Prescott, Arizona, says that the Legacy may have clipped the bigger jet ’ s horizontal stabiliser — fins that prevent the airplane from pitching up or down. “ A likely reason why the 737 would depart continuous flight and go vertically into the jungle at that speed would be damage or loss of the horizontal stabiliser, ” Mr. Waldock said. Relatives flown over crash site Relatives of the passengers have complained that they were not being informed about the ongoing search for bodies or the investigation. The air force has flown them in groups of six over to the crash site. The air force says that it was to show them how difficult it is to reach the crash site. “ They will be able to see the difficulties of the operation … The place is difficult [to access], there are trees of up to 40 meters (130 feet) tall, ” a spokesman said. “ The debris is scattered so rescue work is even more complicated. ” Worst air disaster in Brazilian history This is the worst air disaster in Brazilian history, surpassing the June 1982 crash of a VASP flight which hit a mountain near Fortaleza in northeastern Brazil, killing 137 people.
