In addition to her feature in the 2014 Sports Illustrated Swimsuit Issue, Kate Upton stars in a playful, floating photo editorial. The simulated zero gravity flight was conducted by Zero Gravity Corporation and was done through a series of 17 parabolas, an old technique used by NASA that involves the plane ascending at a steep angle before slowing, straightening out and then quickly descending at a steep angle. Weightlessness happens between slowing near the top of the arc and pointing the plane straight down at high speed to begin the next parabola.
