Spirit did a little hiring about 10-12 months ago but since then hiring has been pretty slow. I am not sure if Detroit is there Junior base, think it is but cannot remember.
If you do not mind the commute, and would like teaching, FlightSafety Toledo is growing. The salary is above you 40K mark and you get to sleep in your own bed every night.
Sorry I do not have anymore information, but I do have a resume on file with Spirit, and a inter company reference and time well above their minimums and have not heard anything for over a year.
Best of Luck,
