In fact, my posting just above already refers to what Seremet declared during his press conference. The full text can be found on gazeta.pl

From the information above and publically available I see the following:- At 1500m (0,96miles) from the runway they went below the glide slope. ATC advises to abort landing.
- At 1100m prior to the runway they're at 8m (24ft) AGL and hit the first tree.
- First question: there was fog but I understood visibility was less than 400 m and I assume they must have had visual contact with the ground at this stage. Or am I oversimplifying things?
- At 850 m they are 2,5 m (7,5ft) AGL and hit the big tree (probably with the left wing).
- Second question: Roughly 2,5 seconds must have gone between they hit the first tree and the second one. Assuming they would have responded after the first event, applied thrust and tried to abort landing, the inertia of the plane would not allow it to react over such a short distance and time-frame, correct?
In the end, it still is a mystery to me why they were so low.

Another mysterious thing is that the crash happened at 10:56am. I have never in my life yet seen fog that is that bad in late morning. Just pointing out, also it was said that the pilot made 4 landing attempts and then it was said it hit a radio antenna. So what is the trust! Maybe he did not hit the tries first!

Yes, I grew up in such a region (the low countries), where it is very wet. I confirm it is easily possible to have fog at any time of the day although it is obviously more common in the morning. Typically it clears out during the day, but not necessarily.

Originally posted by justLOT787 View PostI think that PAF 101 had good avionics and it probably was working. Doesn’t a warning kick on when they are to low like (danger low terrain, speed, stall some thing in front of you terrain) Those pilots wore one of the best and I don't think they would have made a mistake like this!!

This link explains exactly what happened during the crash. You can paste the text into a translator or there is a translated link on another forum. While the translation is not perfect the photos help make the events clear. http://smolensk.ws/blog/168.html
What the a/c was doing that low in the first place is another matter.

It seems incredible to me!!!!!
I have spoken recently to some aviation experts, and ex pilots on TU 154's, from TAROM (romanian air transport), and they have told me that clipping an antenna is not likely to have been the cause of the crash. The TU 154 is a rugged airplane, designed to land on strips covered in rubble, dirt strips and grass. It seems a little unlikely that the best pilots in the country on this type of airplane would choose to land in CAT III conditions as though it were VFR!
Something else, though, has caught my attention! I have heard the audio of the conversations between the pilots and the ATC countless times on TV, and the pilots keep saying that they are working according to their orders... orders to do what? Descend under the glideslope? Land in next to zero visibility? Get everyone on board killed?
God knows what happened? R.I.P. to all on board!

Few Questions to All here...
Evan said earlier that the pilots would try to make a visual, descending bellow minimums, and taking advantage of radalt equipment, newly installed on the plane.
What would be the approach speed of a TU 154 in such conditions? Guessing somewhere around 140-155 knots, slats and flaps extended.
Now, what would be the angle of attack at such an airspeed? I guess it would be a very nose-up attitude. Going on the same judgement, from were the pilots are sitting, I guess it would be hard to see in front, in perfect conditions, doing a shallow approach, so in fog it is blind flying!
From my flying experience, GPWS is used on any approach, be it VFR, or ILS, or NDB, or VOR! I personally use it in any conditions, cus I feel it lets me know the altitude much better than a copilot. I consider it suicide not to use it in every case.
Furthermore... there is a saying among airline pilots, at least in this neck of the woods, that says like this "300 on the mile", so what the f*** were they doing at 200 ft, more than a mile away from the runway, not to say the threshhold, or TZ. Anyway you look at it, it's suicide!
Hope I made some sence...

Clear to me Vanghell. The high AoA would be a good explanation. With you on that.
Another question from a non-pilot to the experts here. As a pilot, wouldn't you make yourself familiar with the environment of the destination airport before or during the flight? And if so, wouldn't they know about the 'valley' (I'd rather call it a small depression) just prior to the runway? Or would the Jeppesen maps used for the approach typically only highlight large obstacles?
This said, I believe that the same pilot flew the prime minister to Smolensk just days before the accident.

It was my understanding that nothing would be made public until after the return of the Polish prosecutors later this week and if the Russian's would authorize them to do so because it is material that is being used in the criminal investigation.

Gazeta.pl published an interview with general Czaban commenting on the incident. I will summarize some key excerpts of the article to be found here http://tinyurl.com/2annoex
Pilot of crash near Smolensk, Cpt. Arkadiusz Protasiuk, was also with the president in Tbilisi in 2008. - He and his colleagues were called cowards after refusing landing due to bad conditions - said on Radio Zet, General Anatol Czaban, head of Air Force training.
By the way, Czaban confirmed once more that the Cpt. was fluent in Russian.
Another excerpt.
According to the head of training Air Force Gen. Anatol Chabany, the pilot who crashed in Smolensk, might want to check whether the conditions at the airport were really as bad as reported by flight control.
In his opinion the pilot may have had another view of the weather conditions of the land as first pilot Arkadiusz Protasiuk knew that an hour before another plane landed at the airport Smolensk Yak-40 flown by a less experienced pilot, so he wanted to check to see if weather conditions were really bad.
"Nobody trained pilots to risk more than what is in the rules"
Czaban said that Protasiuk already had flown several times to the Smolensk airport. He pointed out that an explanation of why the disaster occurred is the subject of a special commission.
According Chabany, the pilot "had to take into account several factors, such as the importance of Katyn ceremony and the fact that the delegation was late, and therefore" decided to check whether a successful" landing would be feasible. - For some reason he did not decide to divert to another airport - said the general. When asked if there is something like "VIP airplane syndrome" he said: - As I am 32 years in aviation, no one trains pilots to risk more than what is in the regulations.
