vorra, I duly re-read last 20 pages of both forums, Smolensk and aviators general (Russian) and can't find the description of what it is on Yak anymore. I am sorry. Either one or the other - I glanced in at far earlier pages of either forum yest - or - more likely - moderators at both forums post-reactively "clean the branch" (as they say, "I have cleaned this branch as I could, and please in future refrain from what has no relation
to..." etc.
The links:
Smolensk locals, at 234 pages so far
? ????????? ???? ??????? • ?????????? ?????
The main Rus. avia forum, stopped for contributing at page 88 (last page so far)
Катастрофа Ту-154 президента Польши - Страница 88 - Авиационный форум AVIAFORUM.RU
And just in case a small Rus avia forum as well, but just 6 pages
Forumavia.ru - Авторские форумы
That's where I fish :o)
