Another tupolev, the 154 is a Trijet like Boeing 727 and Trident 1c

About the aircraft

Tupolev's Tu-154 tri-jet remains the standard medium range airliner on domestic flights in Russia and other states of the former Soviet Union and to a lesser extent in eastern Europe and Iran. The Tu-154 was developed to replace the turbojet powered Tupolev Tu-104, plus the An-10 and Il-18 turboprops. Design criteria in replacing these three relatively diverse aircraft included the ability to operate from gravel or packed earth airfields, to be able to fly at high altitudes above most Soviet Union air traffic, and good field performance. To meet these aims the initial Tu-154 design featured three Kuznetsov (now KKBM) NK-8 turbofans (which also powered the larger, longer range Il-62) giving a relatively good thrust to weight ratio, triple bogie main undercarriage units which retract into wing pods and a rear engine T-tail configuration. The Tu-154 first flew on October 4 1968. The first production example was delivered to Aeroflot in early 1971, although regular commercial service did not begin until February 1972. Three Kuznetsov powered variants of the Tu-154 were built, the initial Tu-154, the improved Tu-154A with more powerful engines and a higher max takeoff weight, and the Tu-154B with a further increased max takeoff weight. Tu-154S is a freighter version of the Tu-154B. Current production is of the Tu-154M, which first flew in 1982. The major change introduced on the M was the far more economical, quieter and reliable Soloviev (now Aviadvigatel) turbofans. Low rate production continues. Meanwhile the proposed Tu-154M-2 with two PS-90A turbofans remains unbuilt.

About the crash: 2002 Überlingen mid air collision

Aircraft involved

On the night of 1 July 2002, BAL Bashkirian Airlines Flight 2937, a Tupolev Tu-154 passenger jet, and DHL International Aviation ME Flight 611, a Boeing 757 cargo jet, collided in midair over Überlingen, a southern German town on Lake Constance, near the Swiss border.
The official investigation by the German Federal Bureau of Aircraft Accident Investigation (German: Bundesstelle für Flugunfalluntersuchung) (BFU) identified the main cause of the collision to be a number of shortcomings on the part of the Swiss air traffic controller (ATC) service in charge of the sector involved, as well as ambiguities in the procedures regarding the use of the traffic collision avoidance system (TCAS) on board.
A year and a half after the crash, on 24 February 2004, Peter Nielsen, the air traffic controller on duty at the time of the collision, was murdered in an apparent act of revenge by Vitaly Kaloyev, a Russian citizen whose wife and two children had been killed in the accident.

Only one ATC, Peter Nielsen of ACC Zurich, was controlling the airspace through which the aircraft were flying. The other controller on duty was resting in another room for the night. This was against Skyguide's regulations, but had been a common practice for years and was known and tolerated by management. Maintenance work was being carried out on the main radar image processing system, which meant that the controllers were forced to use a fallback system.

The ground-based optical collision warning system, which would have alerted the controller to the pending collision about minutes before it happened, had been switched off for maintenance. Nielsen was unaware of this. Anaural short-term conflict alert warning system released a warning addressed to workstation RE SUED at 23:35:00 (32 seconds before the collision). This warning was not heard by anyone present at that time, although no error in this system could be found in a subsequent technical audit;?however, whether or not this audible warning is functional is not something that is technically logged. Even if Nielsen had heard this warning, at that time finding a useful resolution order by the ATC was impossible.
