“Was there ever an aerial war in our distant past, maybe 2,000 years ago?   An aerial war?   Yes.   There are certain understandings, what you would call treaties between various visiting civilizations, specifying how they are to conduct themselves in contact with humans. Those that did not have the best intentions for Earth applied certain arrangements and pressures to certain civilizations. These aspirations were restrained to create a reasonably safe and neutral area of space that includes Earth and many other planets. This might be what you call aerial warfare.   That is probably it. The reference comes from very old writings in India and a description of ships in the sky, fighting.   I understand the Hindu texts. They give insights into the background of a number of civilizations that have come to Earth. These Indian texts have many clear insights and provide early information on contact with humans.”
