Defense aviation in particular. Still, all three of them are trying to swim with a millstone as long as they have the legacy of the UAW retirement benefits package tied to them. Not that that is all the UAW's fault, the corporations agreed to it without thinking about the freight they would be carrying in the long term, they are as much to blame as the UAW for the situation. Seems like only complete bankruptcy, selling assets without corporate continuity, or Governemtn takeover of their retirement programs are the only things that could ever get them out from under. Moving completely out of Michigan probably wouldn't be a bad idea either.
