I agree with the posters above.
The banks wont look at you, especially in the current financial climate.
My advice would be work hard, save hard and get a PPL. Then if you still want to borrow it at least the banks will take you more seriously.
Alternatively try and get a job at an airfield and maybe you could come to some agreement to get a free/cheap PPL in return for your work.
Take it one step at a time. Concentrate on the PPL now.
