Go for it !!!!!
We all moan about Management, equipment, hours etc. etc.
I have just done 32 years as a Controller with Nats. OK they are a S**t outfit. But the guys you will meet and work with are fantastic. It is hard work training. When you finally get validated and are sitting on your own up to your arse in alluminium you will think 'What the hell am I doing' Go for a beer after work.
Good luck !!
