At about 1100 eastern time, a Piper J3-C65 crashed during a training exercise near Trinca Airport. The flight instructor was seriously injured and the pilot-rated student suffered minor injuries. The pilot was undergoing tailwheel training and was on initial climb after a touch-and-go when the instructor pulled power to simulate an engine failure. The instructor urged the pilot to lower the nose, but the pilot continued to slow the airplane until it stalled and spun into a cornfield.
