People pay more attention to airplane accidents right after a large accident event.. Google plane accidents and you will see that they happen all the time, they just don't get the world wide news coverage.
What's actually a far bigger coincidence is that there were no fatal 777 crashes in the first 20 years of a >1200 aircraft production run until this year, when two aircraft belonging to the same airline were both total losses in apparently unrelated cases of apparent foul play. Whilst I can't conceive any conspiracy theory linking the two that would be credible even by the low standards of the average conspiracy theory, that's a far bigger statistical anomaly.
Yea, I think people will buy that.
It sells better. [1]
