Plane Crash in Perm-a tech problem, issue of old planes still in exploitation or something else?

The plane crash in Russia's town of Perm might be an accident but a few facts seem a bit odd. According to the air traffic controller, the pilots' behavior in the last 20 minutes of the flight was erratic and illogical which might signify that there was a third party in the cockpit. The Perm residents say that some of the larger institutions in the city were alerted to a possibility of a terrorist attack a few days before this happened. If one is to believe Sulim Yamadaev, a commander of the elite pro-federal forces 'East' battalion, formed of the former Chechen militants, now at odds with some of the FSB figures, around 20 young women 'went into the mountains' which means joined forces of the North Caucasus Islamic mujahadeen. We all know that women are mainly used a suicide bombers (only in Tamil Tigers are women equal fighters with the men).

This, of course, is only a suggestion. But if people's lives mean anything to the government it should not keep in jail a man who is able to prevent the loss of innocent human lives. Just a thought.
