Aerospace Engineering Professor Paulo Iscold, right, has built a sailplane he hopes will break speed and distance records. He recently had Jim Payne, left, a record-breaking test pilot, fly the plane for testing at the Paso Robles Municipal Airport. The plane, which Cal Poly students have helped prepare for flight, features a 93-foot wingspan. The plane, named Nixus (“pushing forward” in Latin) is the fourth Iscold has built.
