Hi Dan,
Thanks for your input. Actually I keep watching job postings, and within that, pipeline patrol, but most of them require 1500 PIC time with experience in complex airspaces and low level flight, CPL and IR, and usually they hire locals (they provide no help in relocation). But in a general sense I'd absolutely be interested in such pipeline work (if I'd meet the requirements - but I'm afraid I don't). So, again, the best would be to find a place where I could work as a glider/motorglider instructor and go from there.
