Boeing has a couple of facilities in Ogden. I don’t see any Southwest facilities there.
I worked Minuteman III and Hill AFB at Ogden has a very strong Boeing presence because they are prime on Minuteman and Hill AFB is the maintenance depot for that program.
Lots of that story don't make a lot of sense. How a broken plane that was grounded in Oakland wound up in Ogden is a mystery. Did the reporters screw up Ogden for Oakland?
Boeing would do tear down failure analysis at their factories in Washington or South Carolina and Southwest has their major maintenance depot in Texas. Neither do major commercial maintenance operations in Utah that I know.
If someone out there can explain how the plane got to Ogden please tell us.
