This refers to the plane that crashed today regardless of whether Prigozhin was actually on it or not.

If Putin or a spokesperson on his behalf takes credit or claims he was directly responsible this will resolve yes.

If he implies it was an eg. "unfortunate accident by the Russian military" then this will resolve NO.

If he doesn't make any statement that fulfils either resolution criteria by close date (end of 2023) then this will resolve NO.

In a case where he ambiguously implies he was responsible, but leaves it somewhat open-ended, I will close the market and conduct a poll in our discord that our Trustworthyish users can vote on to determine the resolution. I may re-open the market to trading if they think the statement wasn't strong enough to resolve one way or the other.
