With rest of world taking opposite position, FAA has no choice but to capitulate (if not for technical/safety reason, but for other reasons), regardless of what satellite data and their enhancements say.
However, within 48 hours post 2nd crash, I thought Boeing/FAA was trying quite hard to convince public that it is safe to fly with 737 Max.
We told German that their car have emission problems, we told Chinese their telecom equipment can spy you on mobile networks. For our own planes, we told the world that you need to wait for us as we are data driven. To me this sounds like a convenient excuse.
