Honestly, this is tantamount to negligence by the FAA. This plane should've been grounded immediately and all of them checked for maximum safety. But the US, as dumb as always, just goes "nothing to see here", "we're waiting for data despite the data being 2 crashes where everyone died in 5 months".
So if over 200 people die on your watch in a statistically unlikely event, you're not going to re-check the planes? What makes US and Canadian pilots anymore worse than Indonesian and Ethiopian pilots? In the Indonesian case, it was a known software fault.
