I've always found current Russian airport security to be the equal of that in the west; going through there again this weekend and have no qualms. In fact, it doesn't suffer from the American concern about politically correctness and just intensive searching 1 in every n pax even if they're old ladies; in Russia they go through whoever they please. I presume there are certain social groupings that get checked over every time. So be it.
The 134 in question, for those discussing aircraft age, was built in 1977. Bear in mind that Russian aircraft do nothing like the hours of those in the west. The fairly intact panel in the picture above with the registration on it is the (appears to be port) engine cowling.

Thoughts with the families of those involved.
