Santa Barbara getting MD-11s? No way.
They will keep flying their DC10s until god knows when. They can't afford a new type of equipment and also they don't have qualified mechanics to perform maintenance on MD-11s. Here in Venezuela mechanics only work on DC9s, DC10s and B732 ( only because the B732s have the same engines as the DC9s).
That's why the only jets operated by Venezuelan airlines are DC9s, DC10s and B737-200s.
About the noise regulations in Europe... I have no clue. I don't think they are gonna ban the DC10s, because if they do, Northwest and many cargo airlines will be affected. Maybe in 5-10 years we'll see a ban on older airliners, but not right now.
