I worked in an industry where we were held accountable for the quality of our work. I joked for years, that If I did not screw up on this job, not only did I get paid, but I got another opportunity to not screw up...
But there were not nearly as many lives involved, just more money than I am likely to ever see.
I must note that the problems seem to be happening not only with Boeing built aircraft, but with those in United's fleet.
Does someone have enough of a hard-on for United that they are sabotaging their aircraft?
Maybe someone who knows Boeing's line best? (These aren't necessarily the sort of malfunctions that will be fatal to the airframe, or even most of the passengers, but they are sure headline grabbers.)
Is someone looking to trash United's stock value and buy up a lot of interest in the company (ditto for Boeing, since they seem to be getting a lot of the blame, even for problems with aircraft that have been in service for years).
Is this a result of DEI and hiring people not as competent at maintenance as they are at checking the right boxes?
Are these acts of terrorism by a foreign or domestic group?
One or more of these factors may be at play. Or it could be as simple as needing to drug test the crews who work on the planes.
In the oil industry, there were pre-hire, random, and post-accident drug tests. If anyone got hurt or there was some sort of major malfunction, or even if some just started acting weird, they got tested. (It's a shame we can't do that with Congress and Federal Agencies, not to mention POTUS).
Every crew who worked on these planes should be subject to investigation.
Just saying.
