Amex, I think your missing the point...MOR is frustrated at the Irish CAA (IAA etc big deal!!) that in order for them to keep costs to an absolute minimum for their chums at S*ity-jet, they bend the rules to suit themselves!
As is usual in these kind of arguments, things tend to get personal, however, there does exist a very real perception that in the area of working Visa's and labour laws the US is master of double standards...on the one hand being protectionist, and on the other wanting to impose their regulation on foreign based US registered aircraft. (aka UPS, Polar, and more recently Atlas in the UK where the state department got involved trying to ride rough shot over a host of local UK rules)
