I thought I would actually add a little commentary to this one.
For all my Hard SF Rocketfans out there, the masks provide pure O2 so that the mechanical pressure suits under their clothes don't cause the bends in the event of depressurization. The spaceplane they are traveling on rides along a magnetic track until it ski-jumps off the launch tower. Then the umbrella bell on the tail opens so the rocket can be goosed into space via lightcraft propulsion. There are a couple of solids to boost the plane out of LEO and into a GEO rendezvous.
