A student pilot, who held a rated pilot certificate, and a certified flight instructor (CFI) departed at 1645 Eastern Standard Time for a flight intended to provide experience in a complex aircraft. The planned lesson included maneuvers such as minimum control airspeeds, stalls, steep turns, and emergency procedures.
