That was my question as well.
If it WAS a Max, Being is in REAL trouble. The ‘fixes’ were supposed to have eliminated the problems.
An old 737-500. According to flightaware was only in the air for about 4 minutes, turned right on-course, then crashed just offshore. ADS-B data can be suspect but showed pretty high climb rates(almost 4k/min.)before it fell like a rock(12k/min). Speed data seems low for that kind of drop, but again, it’s ADS-B data.
