I knew that would come up, which is why I previously posted the case where an SR-71 failed to out-climb a thunderstorm and was destroyed, plus the case in Japan of an A-4 caught in clear air turbulence that was nearly destroyed. A thunderstorm can best any production aircraft ever made. I think the airframe of Chuck Yeager's X-1 was stressed to 25 g, I guess it could survive most things but it's not a production aircraft.
I believe that SR-71 was lost because both engines flamed out inside the TRW, rather than structural failure. It makes me think of the DC-9 that crashed trying to land on a narrow, tree-lined Georgia road after both engines was destroyed inside a TRW. But, they came out the other side intact.
The engines at issue should be of considerable interest to the investigators.
