Please do follow objective information and do not copy nor coment dezinformation info. Stay on the correct info. without it it will be difficult to get out the truth. Two planes had navigation problems that day: Russian IL-76 coming to land first and Polish TU-154M Lux (101-Presidential). Both planes were separated in time about 1.5minutes between each other. Both planes were almoest in the same wrong place, height and course (the cut trees and electric power line are an objective wittness). Question is, why Polish TU-154M Lux after second NBD landing marker changed correct course to the incorrect one. Turning left about 15 degrees from the axis of the runway and decreasing height suddenly 6m/s in the same time??? Without that change the plane would touch down at the begining edge of runway and there would not be any tragedy. Why the airplane Autopilot was fed with the error datas flight course (autopilot turned off 5-6sek. before the crash - in the moment when pilots realized that they will hit the ground and tryed to pull-up)??? Pleas e turn your attention to the wright problems in this trgedy. My personal credits to the Russian Govaermant Officials for handling this tragedy at the begining.

By my opinion the theme of incompatibility is only dummy problem. The main is absolute incompetence in preparing the travel. Fly for the last moment without having any alternative, board so many important members together on one plane. What to think about army command, allowing so many important people to fly together. There is no reason to think about any bug made on Russian side. Impeach reliability of Russian landing system is only "politicum" reasons of accuracy is commonly uncertain, always relative to the chosen axioms. More important is simplicity. And all meanwhile released news about the fly show, that Russian flight control follow this main rule: "Simple is better than easy". Instruction was clear: "not to land". Delay of ceremony wasn't so important. I believe that the flight recorders give the reliable data and they will be released without "transformation" to the information by request.

I agree with Capt. Winkler, above, about why the pilot would even consider such a dangerous landing. Certainly. a visual approach in fog!! Back in the 1990s a jet carrying the U.S. Secretary of Commerce ( Ron Brown ) tried a visual approach (VFR) into Zagreb, Croatia. It hit a mountain. Experts agreed that the Zagreb Airport was unfit for commercial jets. The ICAO should classify airports, such as those in internal Russia, by their navigation systems and facilities. AND RUSSIA should upgrade their facilities at some airports, or restrict / limit international flights into older domestic airports.
