I was at Northbrook from 90-92 and did the Aircraft Maint Course. It was a great way to learn all about Aircraft Maintenance, the college has also good contacts for getting you work experience on Aircraft.i It was a great start to my career and I worked in Engineering until 1999, when got my first flying job. Since then I have flown for a few companies and employers always liked the fact that I had my Engineering background. If your son wants a career in aviation its a great way to start, and then he can decide his path.
Hope that helps.FM
