How would that work?
Also, could the log thing work in some way? If I have a bottle of compressed air that vents at a known (or that someone with math skills can figure out) could I fire a projectile straight behind me, then measure the diff...
Wait, no. It would still give me the speed relative to the ship and I would need to see it from an outside frame.
I think I leave that thought process there though, just in case others had a similar thought, and for the fact, that I really did figure it out as I typed it.
