I worked in experiential. Engineers are people, they make mistakes and they aren't on the airplane. You are. There are people out there that can and will kill you and will go home after work.

I flew Maintenance Flight Test for American. Found the 707 300 series stalled before stick shaker. I was told I did not know how to stall a 707, I had stalled the 707 many times testing them.. Another American Test Pilot had it stall before stick shaker. American Test Pilots didn't know how to stall a 707. Boeing Test Pilots came to test the 707 and fell out of the sky with no stall warning. Turns out nearly 100 707 300s around the earth had been fitted with the 707 100 stall warning and they had been flying that way for 15 years.

I like Boeing a lot, but they are people, not geniuses and people make mistakes. You'll be the first to hit the ground. Demand to be heard and trust yourself, you'll likely find you know more about flying then the experts.
