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

A check against the trajectory and end point of the balloon flight was made by a group of graduate students of meteorology at New York University. By constructing constant-pressure maps from the appropriate radiosonde data, the expected trajectory was computed assuming the balloon would move with the geostrophic wind. The results of this comparison (Figure 21) show that the balloon tends to move across the isobars toward lower pressure. Figure 21
