there's no good alternative at all in sight...one of those could well be jet travel...I'm not sure if I mentioned it, but my Dad was an airline pilot after the war, and my sister flew commuter and corporate jets...very likely to an airport near you. I have no illusions about how that industry will be powered in the foreseeable future...so move your throttle to idle on that score.
I don't know how you assign "elite" status to posters, but I'm a guy with engineering degrees and several years of experience in the nuclear industry...all I'm doing is giving information and opinions that anyone else with my background could/would give...nothing elitist about that...btw, I'm sure you're 'elite' in your field.
