If the Ford plant goes, it's going to hurt.
That's quite a long-term thing. But I also think that Ford is doing a lot of work in that area anyway. They're not amateurs, they've been working on hybrids and other fuel systems for a long period of time -- all those manufacturers have been. So they might be interested.
I think it will take about 15,000 ordinary jobs to make up for the lost Ford jobs.
