Thank you, Mr. Robinson.
You required several physical changes to the MAX 8 above and beyond the FAA's requirements, and that's certainly commendable. My question is why you stopped short of requiring a third angle of attack sensor. I understand that this is something that was recommended by several independent experts. It's something that's used in the Airbus A320neo.
What were the factors that went into that decision not to require a third sensor, and were there concerns expressed by Boeing related to that possible change?
