As well, after reading your FAQ, to have a complete theory you need to be able to answer the most basic questions. Why have you left some of these questions unanswered? The coriolis effect? Why the hull of a ship disappears over the horizon before the mast? These are proven effects of a round earth. To not have an explanation for these questions, leaves holes wide enough in your theory to fly a 747 through.
Edit: And for the record, if the earth is accelerating upward at 1g, and someone jumped off the side of a Flat-Earth it would not accelerate upward past you. Because you would be moving at the same speed relative to the earth itself, you would stay in position floating beside it.
Remember, there's no air resistance in space, so would stay at that same acceleration.
