***Both planes were flying at a great speed when they crashed — another flaw, according to Lemme because MCAS should have stopped at that speed.
"There is no way to stall the airplane at that airspeed and MCAS should have had logic in place that would prohibit it from operating," Lemme said.

Lemme said testing should have caught the problems with MCAS.
"That should have been found. You would expect the test program would look at the likely failure modes," he said. "That is a breakdown in the test program."...

Isn't that statement a logical fallacy for two reasons:
- An aircraft can stall at any speed, if the altitude is sufficiently high, and the the wings are in a banked turn (accelerated stall).
- MCAS is not an anti-stall system, so that statement has no bearing on its activation.
