Mr. Bertorelli has consistently written about the MAX in a vitriolic fashion. It is a truth that a second vane input should have been an input for MCAS. It is also a truth that both of these accidents could have been prevented had the pilots used their left thumb. Boeing was in the process of re-working the MCAS when the second accident occurred and had issued bulletins to operators. The final accident reports and findings are not complete in either of these accidents. In either case a blame game does not serve safety. Yup…its the fault of the software designers. Right.
