> Airlines operate to a much stricter standard than one in a million. If one in a million flights ended in a fatal crash, the US alone would see about 3 airline passenger deaths per day on average.

I think you conflated flights (several 10Ks per day) with passengers (several million per day).

One in a million flights is one accident every few decades.

> at least in the US. Engines will fail

As per the report, this appears to be a structural failure, not an engine failure.

If randomly distributed, one in a million flights crashing and killing all passengers means that one in a million passengers dies.

The US sees about 25,000 airline flights per day, or around 9 million per year. So with one in a million flights crashing, we'd expect roughly 9 crashes per year.
