The article directly quotes him as saying, "I don’t know that understanding the system would have changed the outcome of this." The "this" refers to a deadly crash in which everyone died. He is saying that if a pilot knew about MCAS, the plane still would have crashed. He said this in response to a claim that pilots didn't need to know about MCAS. That is disagreeing by using sarcasm. The Times interprets it though as agreeing and doesn't see the sarcasm.
To summarize:
Claim: Pilots don't need to know about MCAS.
Response: Correct, even if they knew, given the system's flawed design, everyone still would have died in this case, so, technically, knowing about it wouldn't have helped.
Now maybe that's not what he meant. But it looks like he did. I don't believe that the context of the conversation supports an interpretation that he was agreeing that sufficiently skilled pilots would not have crashed whether or not they knew about MCAS given that he refers to "the outcome of this" not changing, the "outcome of this" being the crash.
- cptskippy 7y agoWhat part if that is sarcasm? If anything he's saying a failed AOT sensor means a fatal crash regardless of whether you know why or not. Which is alarming and terrifying.
- FabHK 7y agoGiven that he's a Boeing test pilot (and in the context of agreeing with the VP), his take would probably be that pilots should have followed the good old Stab Trim Runaway checklist, and all would've been fine (whether or not you know about MCAS).
- cptskippy 7y agoI am genuinely confused though about how his remarks we're sarcastic.

- FabHK 7y agoI agree with you that the test pilot's remarks were not sarcastic. However, you write "he's saying a failed AOT sensor means a fatal crash regardless of whether you know why or not", and I disagree with that. He's saying a failed AoA sensor invoking MCAS can be fixed like any other Stab Trim Runaway, regardless of what you know about MCAS.
- salawat 7y agoExcept that it doesn't manifest like a classic Stabilizer Trim Runaway. The classic Stabilizer Trim Runaway is a continuous uncommanded actuation of the trim mechanism on a particular direction. Catastrophic MCAS failure manifests as a series of discrete, amplifying activations, which are far easier for a pilot to dismiss as the normal operation of the Auto-Trim, and speed trim systems. The is is a manifestly different pattern to look for, and was only caught by one air crew (on the penultimate flight of the Lion Air aircraft) by the assistance of a third, uninvolved pilot along for the ride. I understand how one could see Boeing's internal test pilot as being reasonable, but keep in mind who signs his paycheck, and future prospects for him if the company gets found liable. Perspective, and understanding of what different parties have at stake is essential in evaluating what is actually being communicated, and why. Words have long tails in the aftermath of a crisis like this.
- FabHK 7y agoYes, agreed with everything. I don't think Boeing's test pilot's dismissal (basically: they had their checklists, and knowing about MCAS wouldn't have made a difference) was reasonable, but neither do I think it was sarcastic.
