Like this Osi, from one of the 5 links I posted today, this from The Lufthansa pilot:
"Time and again it is stated that the SU 25 has a maximum flight altitude of 7,000 meters and that’s why this jet couldn’t be able to bring down MH 017. Seeking for an answer on Wikipedia – this statement will be confirmed. If you go to the trouble of broadening your knowledge by questioning a specialist book, you’ll get completely different information: the maximum flight altitude of the SU 25 is 14,600 meters. Check here:

Until beginning of july 2014 Wikipedia gave the maximum flight altitude for the SU 25 with “ca. 10.000 Meters”. As well in the english version as in the german one. Now one finds it “corrected” to 7.000 meters. In the Wikipedia discussions-forum roared up an intensive discussion about the correct value.
The handbook “Flugzeuge der Welt” by W. Green (1984), a standard work which essentially quotes the facts of the military “Janes Manuals” (also used to be NATO reference), already 1984 determined the maximum flight altitude of SU 25 (SU 25 MK, export version) with 10,670 meters (page 208 f.). The performance of the SU 25 has been upgraded since that time."
