When William Knudsen, president of General Motors (the world’s largest corporation), visited London to check on his company’s interests there, he found the population “scared stiff.” “Airplanes! Airplanes!

Gas masks were being handed out by the thousands. “It was really bad,” Knudsen said. “They were just hysterical.”
