NATCO, the NWA General Offices and eventually flight attendant training were all located at the Eagan campus. I am sure
DL is glad to be rid of the things even if they did have to sell them at a bargain price. Like most things
NW did they were functional--not ostentatious--and did what they were intended to do.
Building F never had any
NW markings on it to the best of my knowledge.
NW was happy that most people did not know that it was theirs since it was mostly just a training facility but it did include crew scheduling, inflight service management offices and in the early 80's revenue accounting was there. You used to see carts full of thousands of used tickets in the halls and elevator.
Building C was
RC's corporate headquarters and eventually
NW reservations moved in there when Building A (the ugly green windowless lump attached to the hangars) was demolished. Most of us long-time
NW folks remember that building as the place that we were hired. It also had a killer employees cafeteria.
