I hesitate to even say something, in deference to the much more knowledgeable folks working this at the NTSB and sister agencies right now.

But I'd be surprised if it were that simple, especially given the airtime of all planes flown. Airtime which I'd assume passed largely without incident, as by now some news agency should have drug up any similar close calls.

If we're doing wild speculation, I'd bet on something like the Tesla battery punctures (where it turned out high-energy impacts from pointed road debris were more common than expected).

E.g. a maintenance issue, coupled with a specific configuration, coupled with pilot behavior

Or, it could just be a poorly maintained plane and a freak accident. But that's what root cause analysis and black box recordings are designed to ascertain.
