I saw that documentary video from Al JaZeera (cannot recall when I saw it or in what country) and it did make me concerned about aircraft built in South Carolina versus the main factory in Washington. The rampant drug use while people were on duty was shocking as well as the poor quality of employees building the aircraft.
Is it possible to find out where various aircraft were built?
I flew on my first 787 in May, 2018 and the flight was amazing due to minimal to no turbulence and the cabin pressure making jet lag much better.
But still.
My next trip on a 787 is in March with BA.
