Researcher Long Yip inspects the full-scale model of the Varieze during tests in 1981. The left side of the model has been painted to enhance flow visualization, and wool tufts were affixed to the wing upper surface for flow-visualization tests. Note the discontinuous leading-edge droop segments added to the wing for the study. (NASA L-81-7333)
