Please answer the following question: A friend asked me to answer this question: What is the full name of the person who is unaware that heavy snow has closed the Chicago landing field?, using the article: On May 19, 1927, after waiting for a week for the rain to stop on Long Island, New York, pilot Charles A. "Slim" Lindbergh tries to sleep in a hotel near Roosevelt Field, before his transatlantic flight from New York to Paris. His friend Frank Mahoney guards his hotel room door from reporters. Unable to sleep, Lindbergh reminisces about his time as an airmail pilot. Flying to Chicago in winter, "Slim" lands his old de Havilland biplane at a small airfield to refuel. Despite bad weather, he takes off, unaware that heavy snow has closed the Chicago landing field. Lindbergh bails out in a storm after running out of fuel. Recovering mail from his crashed DH-4, he continues to Chicago by train. A salesman tells him two airmen just died competing for the Orteig Prize for the first nonstop flight from New York City to Paris. Lindbergh calls Columbia Aircraft Corporation in New York from a small diner at the Lambert-St. Louis Flying Field. Quoted a price of $15,000 ($220,000 today) for a Bellanca high-wing monoplane, "Slim" lobbies St. Louis financiers with a plan to fly the Atlantic in 40 hours in a stripped-down, single-engine aircraft. The backers are excited by Lindbergh's vision and dub the venture Spirit of St. Louis. When the Bellanca deal falls apart because Columbia insists on selecting the pilot, Lindbergh approaches Ryan Aeronautical Company, a small manufacturer in San Diego, California. Frank Mahoney, the company's owner and president, promises to build a suitable monoplane in just 90 days. With Ryan's chief engineer Donald Hall, a design takes shape. To decrease weight, "Slim" refuses to install a radio or other heavy equipment, even a parachute, and plans to navigate by "dead reckoning". With no autopilot function Lindbergh cannot sleep during the flight. Workers at the factory agree to work around-the-clock to complete the monoplane in less than 90 days., what would be the answer ?
A:
Charles A. "Slim" Lindbergh
