Your journey of 10,000 Miles start with a first step. Gather the funds for your PPL and do this part time at a local (ish) airport.
After completion make an honest assessment to how difficult/easy it has been to balance work/family and training.
Will you be able to do this for another 2-3 years of part time training?
As you progress the road will reveal itself.
Possible training in Canada, the US or South Africa. License conversions to EASA.
Your job opportunities will likely be outside of the UK.
