Because….
…some pilots don´t have the necessary hours to fly offshore….
…some pilots are fresh out of the military….and can´t find anything else…
…some pilots just "want to" do a job like this….
You put a job posting online…there will be always some pilots desperately trying to get this job..
Tough industry!
(But i would not do this job for that money either….not even for 160k)..
