I would also add that Boeing Renton (narrow body aircraft - 737 exclusively for the last 20 years) and Boeing Everett (widebody aircraft) are very different, almost as if they were different companies. Yes, there is intermix and crossover, but the environments are very different. After spending most of my career working Everett aircraft, I was moved to the 757-737 for a few years and was quite frankly astounded at the differences.
A
rapid production rate in Everett is 8.3 aircraft per month (777 for a few years) - Renton is around 2 aircraft per day. I don't want to say production is relaxed in Everett (it's not), but it's
nothing like what goes on in Renton.
Yes, the MAX has been something of a cluster
, only a fool would assume the 777X will experience similar issues.
