Taken For A Ride Which Isn't Over Yet

In the ten part Steven Speilberg tv series, Taken, the first thing you notice is that there are certain 'givens' up front. Like, 1948, Roswell, there was a crash, occupants were taken and they did have a captured ufo but they couldn't find any motor in it. Fifty years of parallel fictionalized events are covered in the series based on actual news reports, books, magazines, movies. Another given is the utter and total acceptance that the government knows all and is in fear of releasing the info to the public in case of panic or more clandestine reasons. But surely if this were true we wouldn't be spending several kings' ransoms with rockets to the moon and beyond.
Well, maybe not. If we switched to gravity control instead of the oil industry's combustible engine, whether it had been in the fifties, sixties or today, the logic might be that we'd throw the whole world out of whack, economically. Might be true but I think we can handle it. I'm sure we could wing it and muddle through. There may be more fiction out there than we thought. But it's leading us anyway to the quest for gravity control. With the way things are, sooner would be better than later, while we still have a choice.
