Resolves YES if by close date a relevant official body of the Russian federation or Chechen republic accept most of the responsibility for the crash.

Relevant bodies include: president, parliament, air crash investigation bodies

Doesn't include: individual investigators speaking for themselves, bloggers, journalists

The statement must acknowledge that Russian/Chechen actions were a primary cause of the crash, but need not admit complete responsibility (so e.g. "Yes, it was hit by out missile, but if the crew immediately cooperated with our air traffic controllers, the plane would have landed safely" or "the plane wouldn't be hit if it followed XXX procedures" resolves YES)

I will not trade due to the soft resolution criteria.
