My only other comment is if you want to fly for a living you are going to do this anyway irrespective of the current economic circumstances.
I don't think you can plan your training to coincide with a boom or bust because the market is too unpredictable; if you start to train at the time of a boom the industry is likely to be at a downturn by the time you finish. Consequently there are those that trained when industry was looking bleak hence when the upturned occured were ready to step into the market.
If any of us had thought about the whole thing in a rational way then none of us would probably have done this.
