The pilot gave an order to the co-pilot after the former communicated with the air-traffic controllers at Beirut’s International Rafik Hariri Airport. Data analysis revealed that the co-pilot did not carry out the order or undertook an opposite action. Believing that the co-pilot complied with the instructions, the pilot consequently lost control of the plane.
That doesn't really make any sense to me. Does anyone know what ' order' or 'action' they might be talking about or how that could lead to the other pilot losing control?
