You could try HSBC but I think they are lowering their Prof Pilot loans from £50k to £25k dur to so many pilots declaring themselves bankrupt. HSBC only offer this loan to OAT and FTE
or CTC students. This is only what I have read on this forum mind.
Good luck. Not sure CTC would be too impressed that you can't plan your finances though. If you can't plan where to find £60k before wasting their time I am not so sure they will have the confidence in you to plan a transatlantic flight
