Without having maintenance data, which won't be publicly available, it's really impossible to know the probability of dual engine failure. The Navy may be different but usually if there is any way to hang it on the crew they will be the ones blamed. This latest F-22 debacle is a great example of how that goes. If the safety investigation comes back with the determination that it was an unfortunate coincidence of two concurrent malfunctions then I would be inclined to believe it.
Glad to know that people who know more than I do are not suspicious of maintenance as a factor. The short article didn't rule it out nor mention it as a possible factor, that seems like an obvious question for a journalist to ask and mention in the article. What passes for journalism is scary, on the interwebz or otherwise.
It's really hard to know what actually went down. Occasionally the truth will slip out but more often than not it is obscured by a variety of factors. You still coming out in a few weeks? We can talk on the drive out to the silo
