I am not sure what conclusion can we draw from, as you said, two very rare incidents over a long period of time.
Reminds me of when Malaysian airlines crashed two planes in a short period of time. It was a good time to get cheap flights from Europe to south east Asia as long as you can withstand relatives thinking you are literally going to die in their third crash.
Bit of an odd comparison, given that one of those flights (MH17) was shot down by a Russian Buk squad. That was not an issue attributable to the carrier in any way, and after the incident the likelihood of it happening again to Malaysia Airlines specifically was negligible.
