samee,
my advice would be to apply for the NetJets scheme at OAA.
Then by all means borrow against the 'rents house as your on a shoe-in for a c.£40k salary from which NJ will deduct/reclaim your training costs.
Toughest integrated course to make it onto by all accounts (including mine! failed..) but what a job! and for such minimal financial risk.
Think about it... when the !!!!! hits the fan, who does it affect more... mass transit of lower income folk to the costa's.. or millionares/billionaires wanting to fly at their convenience?
