Keep pursung your dream, but always have a backup plan. Look around you. Overwater, Pilot-less cargo flight is well within reach of your generation, probably more towards your mid-career point, but quite possibly much sooner than you think. Long haul cargo is hard on your body. Long periods of sitting=boredom, multiple tme zones.. It's not as glamorous as it seems. Passenger flight with pilot-less aircraft is probably farther down the road in the future, due to our comfort level with "Hal"...

Great movie BTW, if you have not seen it... 2001 A Space Odyssey.
