The Roswell Report: Fact vs. Fiction in the New Mexico Desert

23. In this study four flights were made to study conditions at altitudes of 45,000 and 60,000 ft. A clock timer was set to cause release of ballast after the system had floated at the lower level for one hour. After ballast was expended the timer caused release of the ballast tank to further reduce the load on the systems. A typical flight of this series is shown as Fig. 15. Further detail on this study have been given in reports on "Neutron Intensity Study"(5) by this Research Division. [figure] Fig. 15 "Two Level" Stepped Flight
