I'm on the Northrop Grumman Interview Team and work the F35 Production Line as a 2nd Level Manager. I can tell you we are hiring a bunch of people.
You can come in as a trainee (very rare) by taking 3 classes at the local Antelope Valley College. It gets you in the door for a very long term program. You would have to be willing to relocate to near the Antelope Valley.
Obviously having mechanical ability is a huge plus.
Company also pays $15k a year towards a Degree in any type of related field.
As well, the F35 Program is not the only program in Palmdale, there are several on the site to include Black World Programs such as B2, Hale and others I can't mention...
The Antelope Valley has some nice Mountain Biking, as well, you are near Wrightwood, Kernville, Downeyville (sort of), Big Bear (2 hours), Mammoth (4 1/2 hours), where there is some excellent singletrack.
So there is opportunity if you want to invest in a long term plan...
Man! I sound like a recruiter...
