Flying Geologists
Hmmh, now with the uber-loitering endurance on a DA42 with fancy kit underneath you could do some very interesting things...
Tell you what got me thinking....
Chartered a C210 in the Australian Outback last year to go & shoot some footage of Lake Eyre (an analogue of a petroleum reservoir I was working on in Algeria, if you must know...) & the owner of the company who was flying us told me that if I went off & got myself an Australian CPL he would probably give me a job on the spot.
Over-qualified pilots (even prepared to go & live in the desert!) are ten-a-penny, but it was the geologist bit he was interested in...
I should probably point out I have 250HTT & only a PPL.
