Sleeves,
Two thumbs up!
I've got an acquaintance who has worked - on and off - for Boeing for decades. He's an engineer and they treat him like a migrant worker. He was a non-union type as a young man and a staunch union man now. 30 years of getting whipsawed changed his tune.
The first 777 rolled off the line ready to fly. All the components and assemblies bolted right up with minimal modification. Compare that with the 787, and now the MAX fiasco. Unions didn't screw that company up and make those $hort $ighted decisions, management did.
