B2N2, you are so right but Plan A is for dad to give up work in one well paid job and take up a better paid one but without prospects. Son will then walk the straight and narrow.
Plan B.
AFAIK there is no Plan B.
The lad is well set, all his limbs are on the right way up, he doesn't wear glasses, but I have no idea if he has even considered a CAA medical as vital to his ambitions.
I think one motive for Plan A was to avoid 'wasting' time and money on a university education.
Your Plan B is clearly the more sensible option to which I would add, get a medical.
