The Skyhook is far safer and cheaper than conventional rockets! Rotating in space and dipping into the Earth's atmosphere at the speed of a Concorde.
With electrodynamic propulsion, there are no wasted gases. We use Earth's magnetic field to boost us up after inserting a payload into an orbit.
After just a few launches, saved launch costs will exceed total development costs of the Skyhook. Hundred-million-dollar-plus launch vehicles are no longer necessary!
