THE All-YELLOW "Yellow Jacket" is a single-seat sportsplane designed and built by the brothers Bruce and Gilbert Pitt of Milwaukee, Wisconsin. Since this photograph was taken, "bullet" cowls have been added to streamline the jutting four cylinders of the 85-h.p . Continental C-85-8 motor. The balanced proportions of the overall design belie the dimensions - span 14 ft. and length 19 ft . The wingtips and tail assembly have chord-wise black stripes in imitation of the "Yellow Jacket" - a trans-Atlantic cousin to our own British picnic wasp. The Pitt Yellow Jacket prototype (N5745N-exp'l.) has clocked 150 m.p.h . and cruises comfortably at 130 m.p.h.
