One thing I am beginning to understand is that once you are inside of an electro-gravitic field that gravity has zero effect on the craft and whatever is inside. There is no up or down unless you look outside or use instruments to see where you are. Being in a non gravity field, time as we know it changes. You should be in what I call Space time or actual solar time like in a place between galaxies with zero gravity.
The propulsion system that Lazar talks about is both electrical and mechanical. They need to move at least 2 gravitator arms to a point ahead of them to ride the field in that direction.
These are mechanical, hence need time to move and focus. Even if they are very swift at doing this it can not be instant, we just see it being this way because we are seeing it in our time. If we could see it in there time we would see them slow down and stop change directions and take off again. Maybe it would take them a split second or two their time. To us, it would be instant.
