Stratolaunch is far away from anything human related. There are a couple competitors who want to lift a couple 100kg to LEO by 2020. They have not even built their own rocket yet and so far their efforts in that direction have not impressed progressed fast. It will be 10+ years before the launch a human, if ever. Given the existing competition, I don't think they will ever get there. Outside of BlueOrigin and maybe Virgin Galactic are close to human suborbital flight.
