It is of course his privilege to have that opinion. It's unfortunate, however. Without disrespecting Mr. Primeau's credentials, to be fair, he has not been privy to the literally thousands of hours that my team has put into investigating, in explicit detail, the failure modes and the system as it failed, and how we have developed in collaboration with the FAA a series of fixes. He is not privy to all that information. My team is.
