NAFTA etc
For those of us who live in N America, we understand that, unlike the EU which is largely equitable to its members, NAFTA acts very much in the interests of the USA, usually at the expense of the other members......
The US FARs require that US operators or majority owned within the US (70% I think).
Similar rules supposedly apply within the EU - not on a nation by nation basis, but within the EU. As I remember, the only reason CHC managed to acquire HS/Scotia was due to it's Chairman managing to demonstrate some Irish (and therefore EU) heritige..... I seem to remember that this was rather questioned at the time....
