I've still got 1.5 years to go in Scandinavia before I can even start about training back in the UK.
In that case, the prospects for someone with only a tower rating will be much better than NikNaks rather apocalyptic assessment suggests. In 1.5 years the supply of tower-only Nats rejects will have dried up completely. Even now, it's far from impossible. I know several people who have found employment with only a tower ticket, at both procedural and radar equipped airports.
