We had considered making a cannon that used ignited hair spray as apropellant but after a bit of research discovered that air pressure was far more effective.
After setting a record mission rate of seven flights in 2009, launch attempts in the early months of this year experienced a series of frustrating postponements as engineers grappled with a faulty pressure regulator on the rocket's propellant system.
It would take off horizontally from a runway and go straight to orbit without the need for the multiple propellant stages seen in today's throw-away launchers.
