A deadly plane crash in McKinney resulted from a left engine failure during a test flight of avionics equipment, killing pilot Michael Lewis and passenger Gustavo Moreno, with another passenger, Randy Williams, critically injured. The single-engine aircraft, owned by Hunger Relief Ministries, crashed into a gravel mound shortly after takeoff from McKinney National Airport. Witnesses reported hearing the engine falter, leading to a loss of power and the plane rolling upside down before impact. The National Transportation Safety Board is investigating the incident to determine the exact cause, with findings expected to be released in the coming months.
