10 Worst aircraft accidents and incidents

Two 747s waiting at Los Rodeos were Pan Am 1736 and KLM (a Dutch airline) 4805. As soon as the Gran Canaria airport reopened, the Pan Am was ready to leave. However, the captain of the KLM had decided to refuel at Los Rodeos, apparently to save time since he was in a hurry to get home, and the plane was blocking the Pan Am from getting onto the runway. Refueling both kept the Pan Am behind the KLM and made time for a heavy fog to set in.
