As with that Black Hawk, it won't totally be unmanned. It could go from 2 pilots to 1 and that's what has my attention. If you could take an airliner from 2 pilots to 1 or a 4 man 777/767/340/380/747 to 2, then the previous pilot shortage numbers can be sliced in half.

Even now, you could scoff at the idea of un-modified airliner going from two to single pilot or just go look at line check airman training at most airlines or just ask them if theyve ever flown 'single pilot'.
