@sm85 - Yeah looking at it again it is more like £90K!!! So even with a £27K loan it's still a stupidly high amount of money.
I also share all you concerns about the money.
The biggest problem in my mind is that if you failed to get a flying job, which is a distinct possibility, then the money invested in training is pretty much wasted money because the training is only useful for being a pilot. It would be less scary if there was another option open to you if you failed to find a flying job.
