Today Paul Pepper welcomes back MELANIE KNOCKE and REX BELTZ, who are fresh off their trip aboard NASA's Stratospheric Observatory for Infrared Astronomy, or SOFIA, a modified Boeing 747 with a 100" telescope on board. Melanie and Rex take us behind the scenes of this "trip of a lifetime," which consisted of two, almost 10-hour flights off the coast of Southern California. December 7, 2016
