Could we PLEASE stop this discussion on Russian vs. US technology that is rapidly deteriorating into the ridiculous!

From what we know the make of the airplane played very little if any role in the accident. Yes, it was a 20 year old TU5. Yes, it was completely overhauled last year. Yes, it was outfitted with western instrumentation including FMC, EGPWS, TCASII, etc. No, it was not outfitted with RR engines (some twit confused the Tu-154 with the Tu-204).

So far from what seems to be known, the accident has all the hallmarks of a dozen or so similar events when a non precision approach in marginal weather placed the aircraft to a position it had no intention of getting to. The last one was just two weeks ago at DME...

At the moment the critical questions we should be asking (and hopefully getting answers soon):

* What kind of approach did they fly ? We know there is no ILS, there is a NDB but doing a NDB approach with 500m vis is suicidal. The crew were professional, even under pressure to land it is extremely unlikely that they would have done someting like that. Most likely they were flying a PAR approach, but at this moment we do not know. Language very unlikely to have been an issue, all Tu pilots would have received their type training in Russia, language proficiency was one of the selection criteria.
* Did they really make 4 approaches ? There have been suggestions that they only circled the field 4 times, that sounds more like holding over the field waiting for the weather to improve. If indeed there were 3 prior missed approaches, then the event hovers at or is beyond the definition of being reckless, and would be a strong indication of the kind of pressure the crew were under to land.
* Are the reports of wreckage found away from the main impact site true, and if so are they indicative of a tree strike at that point, or are they supportive of an in-flight failure (engine or other).

All these questions are pretty simple to answer, even on the first day of an investigation. Mr. Putin, we are waiting!

Spot on Andrasz, kösenem!

The pressure from the cabin in an executive aviation environment can be very bad and makes you think 3 times before you decide not to try... (never been in the military but could imagine that is even more of a problem there)

Lets hope it won´t come to a fight and slagging contest between Russia and Poland over the investigation. Their relations are bad enough, with Kaczynski being a major contributor to the unrest between them.
