I watched the second plane hit live on tv as it happen. There were planes. I love a good conspiracy as much as the next guy but this is just crazy haha
I leave in the Houston area too. I've too have seen the a plane stop in mid air for a few seconds. I thought I was just tired and my eyes and mind were just reacting slowly, but now that you mention the same thing, maybe there's something more to it.
I'm less convinced with the cave paintings because some seem a little too much of a stretch. But the paintings, its clear that some of them are depicting something very odd, to say the least. It gives me chills, just thinking about it.
