Investigators are examining turbulence as one of the possible causes of the Turkish Airlines as a Turkish pilot association blamed the crash on a large plane landing at the same airport miuFred Sanders, a spokesman for the Dutch Safety Authority investigation team, also said that the wreckage that has lain in a muddy field since it plunged out of the sky Wednesday 1.5 km short of the runway could be moved Sunday evening. A Turkish pilots' group claimed that turbulence from a large plane landing at Amsterdam's Schiphol airport shortly before the doomed flight. Turkey Airline Pilots' Association Secretary-General Savas Sen said late Friday that a large Boeing 757 had landed at Schiphol Airport two minutes earlier. Sen said that plane most likely created “wake turbulence” that hampered the Turkish aircraft's landing. Wake turbulence forms behind an aircraft as it passes through the air. “All possible causes are (being) investigated and turbulence is known to have caused problems in the past, so you never know,” Sanders said. The investigators on Saturday continued to analyze flight data and cockpit recordings retrieved from the Boeing 737-800's “black boxes” and hope to be able to give a preliminary cause of the crash next week. In Istanbul, the head of Turkish Airlines' board of directors paid tribute to pilots Hasan Tahsin Arisan, Olgay Ozgur and Murat Sezer and flight attendant Ulvi Murat Eskin at their funerals. Candan Karlitekin said that, of the 135 people on board, 126 survived due to the pilots' skills. Pieter van Vollenhoven, head of the Dutch agency investigating the crash, has said that the plane fell almost vertically from the sky, which pointed toward its engines having stopped. He said a reason for that had not yet been established. Other possible causes under investigation include weather-related factors, insufficient fuel, loss of fuel, navigational errors, pilot fatigue or bird strikes.

Witnesses on the ground said the plane dropped from about 90 m. It smashed into three pieces as it skidded to a halt in the mud but there was no fire. The airline also denied reports that the plane, which was built in 2002, had had technical problems in the days before the accident. The plane underwent routine maintenance Feb. 19, and had to delay a flight Feb. 23 - the day before the crash - to replace a faulty caution light.
