Interorbital Systems is making final preparations to fire its 7,500-lb-thrust main engine---the propulsion unit that will power all its NEPTUNE launch vehicle CPMs-Common Propulsion Modules--including one that Olav Zipser will ride in his quest to break the world's high altitude jump record---not as a balloon jumper, but as a rocket diver!!! "This is a major readiness milestone for Interorbital--should be spectacular!"
