You don't
have to get into £50k of debt.
Saving up for a PPL / hour building overseas, doing the ATPL's distance learning whilst working, CPL and/or IR abroad or skip the IR and go direct to FI. Sure it's a longer route to take but less of a financial risk than pumping £50k+ into a gamble.
A few of my friends have put themselves into over £100k of debt, with integrated and type rating training. Insane.
