The ATCO trainee program looks very rewarding to me and its guarenteed salary, employment and career. I don't have an interest in planes in the slightest but i do have an interest and experience in technology, radio operating and the military. I did notice that it's possible to get postings with the RAF, so Scuzi is there many postings available with the RAF?
First of all, it is not guaranteed employment. Out of the 31 people who started on my course, only 6 are now valid and there are only 3 left still training out of which 2 should pass. That's 8 people out of 31 who made the grade. Some courses have better pass rates, some worse. I'm not trying to crap on your parade but it is the reality of the situation.
As for the RAF, I do believe there are plenty of ATCO positions. The problem with the RAF is that the salary is crap and the job is completely different. You aren't trained to the same standard and the transition to civil ATC, should you ever wish to do it, isn't easy. If you prefer the military way of life, are happy with the salary and want to do air traffic then the RAF is certainly an option and can be a rewarding career. There's a military controller who posts on here (Trick) who should be able to give you more info about the specifics.
