Hi Reracker
Let me guess, you went on holiday to southern Spain and like many before you, you fell in love with it? Sorry I don't know of any MO's there; there must be one or two I suppose, but most UK aircraft only stage through there, dropping off and picking up the happy holiday makers.
The reason that I reply to this posting is that I have a similar question regarding the work situation in Palma. I would love to live and work in Mallorca, and I have convinced my wife that it would be nice to go over there too. But as a licensed tech with approvals on 757 is there anyone who I could work for in Palma?
