Talk:LOT Polish Airlines Flight 007

message: Article needs some more detail on "the entire US amateur boxing team" - does this mean the Olympic team?  Is there a central organization in the US for amateur boxing; do they have a team; and the article should have a link to this organization if so.  Tempshill (talk) 16:25, 23 March 2009 (UTC)

message: SP-LAA was equipped with four Kuznetsov NK-8-4 engines (not Soloviev D-30KU).  Since this accident was triggered by an uncontained engine failure, it is extremely important to sort this out.
The totally unrelated reference to the Cubana Il-62M with D-30KU engines should be removed as well.

thread_title: Wrong Engine Type

message: This secton is written in a peculiar style, that does not contribute to a clear understanding and could also contain some inexactitudes; I will give some examples:
It says: "In the Kuznetsov NK-8 jet engine, air is sucked from the front of the engine..."
Any aircraft gas turbine receives the inlet air in the same way, so it is unproper to refer this description to the specific model of the engine.
Then it uses a vague term like: "ultra high pressure gases exit the rear of the combustion chamber..."  What is to be meant as "ultra high pressure"? It would be better to just refer to them as "High pressure combustion gases" since the pressure level is not above the so called "high pressure" compressor, or "high Pressure" turbine; since it appears that this engine has two section compressors, two (concentric) shafts, and two turbine sections; which are differenciated by the "low" and "high" terms. Could it be that on this engine the fan section could be understood as a first compressor section?, but that is not usual in common descriptions of aircraft engines in technical english.
(A simplified engine drawing can be seen at: http://www.leteckemotory.cz/motory/nk-8/index.php
which shows a two section compressor.
Inexact description: "Because the engine combustion chamber was still producing power..."  The combustion chamber does not exactly produce power, it produces an increase in gas quantity resulting from the combustion chemical reaction, and more importantly, a considerable temperature increase in the gasses, which increases their volume (flow), and this change is what produces the power when these gasses flow trough the turbine sections.  It is the inertia of the compressor assembly which kept the engine rotating and maintained the pressure and flow for some time after the shaft failed. But how the turbine disc failed and exploded, which is the key part of the article, is not described properly.
Someone with proper knowledge of the sequence of failure could improve the description of this?  Could someone provide a decent drawing of the engine in question, so that we all can see how the suspected shaft is suspended, and where was the location of the shaft rupture?

thread_title: Unclearly written "The engine shaft’s explosive disintegration" section

message: This entry makes statements that vary somewhat from cited information presented on other wikipedia sites about LOT and Ilyushin planes: 
1. LOT Polish Airlines initiated their transatlantic routes in early 1970s. The officials decided to purchase the newly introduced Ilyushin Il-62.
The IL-62 first flight was 1963 and it was introduced early 1967. Regular transAtlantic LOT flights only began in 1973.
2. Many years later it was revealed that after Flight 007's crash, all Il-62s used by Russian officials and VIPs had their engines discreetly replaced with newer ones. 
This was during the time that Aeroflot was carrying out its planned upgrade program to replace the NK-8-4 engines of its original IL-62s with the more powerful D-30 (they had 165 planes). As far as I know, this program began years earlier and all civilian aircraft were upgraded.
3. At one occasion, Polish governmental Il-62M had had specially installed newer engines for a joint Polish-Russian governmental trip to Beijing; after that, the engines were taken back to the USSR.
I couldn't find any record of IL-62Ms ever being used as Polish government transports, although they were used by a number of other countries in that role. The Polish government used two TU-154s (one of which crashed in 2010 at Smolensk). 
Any engine upgrade would have been to D-30s as per the program.
4. The Polish commission report also called for some modernizations in the Il-62 project, most notably doubling the flight controls, so that if one system failed the plane would still be controllable. At the time, redundant controls of this kind were in general use in American and European-made airliners.
Many IL-62Ms did/do have dual controls (although the original base model was single control). 
5. This issue was never addressed by the Russians; none of their Ilyushins of all types had installed an alternate controls.
The other Ilyushin airliners (IL-86 - first flight 1976) and the IL-96 both have multi-control systems, being hydraulic rather than manual.
6. This could partially be attributed to a grudge Russian engineers held against Poles, who purchased their Ilyushins but replaced their radionavigational systems with separately purchased, more modern American ones.)
If this was true the Russians must have held grudges against numerous countries because many of the 42 airlines in over 20 countries which have operated the IL-62 modified their planes in some manner so as to suit their requirements. This includes Cuba, Germany and Czechoslovakia. Some Russian IL-62s have systems from other countries (the EMERCOM plane has Honeywell electronics, and many civilian Russian IL-62s have retro-fitted western audio systems etc).
Finally, it should perhaps be noted somewhere that the engine that failed had reportedly caused unusual vibration problems when previously installed on two other LOT IL-62s before it was fitted to SP-LAA (although an inherent fault wasn't identified at the time). As LOT didn't have facilities to remove or test IL-62 powerplants, the planes were run to their allocated flight hours and had to be flown back to Russia for engine re-fitting. The problem with such a system was that if a potential problem was present (eg an assembly/manufacturing fault) or developed in service (due to wear and tear), it would not always be noticed. After 1987, turbine vibration equipment was used to test turbines at regular intervals.

thread_title: Statements requiring clarification

message: Added some details about the incident itself, as well as about the aftermath. Most of the information come from a Polish documentary about the crash - many original photos, documents shown, witnesses interviewed. Because most details come from this single source, I didn't add any inline citations - I'll made corrections if necessary.

replies: text: LOT Polish Airlines Flight 7 →  – I don't understand why this page was moved in the first place. From LOT Polish Airlines Flight 007 to LOT Flight 7 and to LOT Polish Airlines Flight 7. The original title was already fine. The common name was with the zeroes and all Polish sources define it.
