DING!
Did someone say NAA Dallas??
My dad worked at North American in Dallas during WWII.
It became Vought after the war, then Temco and LTV, and for a while it was Northrop/Grumman now back to Vought. Yes they are building airliner parts and Gulfstream wings.
They have built a lot of airplanes in that plant.
P-51, AT-6, B-24, C-82 (three?) F-4U Corsair,F6U, F7U, F-8, A-7 and a few others.
It is on the southwest side of Dallas next to Mountain Creek Lake. It was attached to Hensley Field which became NAS Dallas. The airfield is now closed except for an Army Guard Chinook operation.
