Ok complete ignorant here regarding SAR - hope will not be tossed under the bus outright
Following this thread for a few weeks now I am still wondering about the 200ft zero vis flying. Is there something technical or procedural into it ? I know the ocean is a big place but there might be quite a few things 200ft above water (such as large marine vessels, offshore windmills, etc)... I am sure they thought that it was perfectly safe but is there any fundamental reason not to elect to fly somewhat higher ?
