Well having spent most of my career abroad and now in the uk i think the industry here needs more aussie and immigrant pilots to dilute the old boy net stangle hold on the industry. (as an example the non qualified airtours chap who got where he did before being found out as he put a certain military flying organisation on his resume. That must have automatically exempted him from a background check.)brit pilots are disadvantaged more by that than immigrants.
As for Balpa well nuf said
