    Lindbergh's daylight and darkness chart

    Charles Lindbergh's May 1927 Daylight and Darkness Flight Graph. One page (two individual graphs glued seamlessly together), 21" x 8.5", n. p., May, 1927. Drawn by Lindbergh in his hand, showing periods of daylight and darkness over the span of four and a half days. Each area of darkness is represented by four diagonal bars, shaded in pencil. The left Y-axis represents New York time and the right Y-axis Paris time, with a difference of seven hours between. The X-axis serves as mileage, beginning at zero at the left edge and increasing, as you move to the right, in increments of 100 miles (the cruising speed of the Spirit was to be about 100 mph); every 500 miles is designated by a bolder vertical line (the first of which, representing 500 miles, is mismarked 5,000). A vertical red line is found at right and designates Paris with an approximate distance of 3,660 miles from New York. Emanating out from the bottom left corner (12 midnight, 0 miles) are fourteen red, semi-dashed lines at different angles, each representing air speed and approximate flight hours. The top line, slowest speed at 70 mph, estimates a total of 52 hours and 40 minutes to reach Paris from New York. Each line, moving downward, increases the rate of speed by five mph, shortening arrival time. The bottom line, at 135 mph, calculates a 27 hour and 10 minute flight time. A separate line, in red and black ink, is shown leaving New York at 5 am local time (the original time for takeoff which was delayed until nearly 8 am due to light rain). The line curves slightly as it travels upward, terminating at the "Paris" line at 3 am Paris time. Four small holes at the left edge; two minor chips at left and right edges. Light, nearly imperceptible, stain near the bottom. Very slight darkening from adhesive where the two pages are connected. None of the flaws affect the text.

    At 7:52 am, May 20, 1927, Charles A. Lindbergh, aboard his specially designed Ryan NYP Spirit of St. Louis, loaded down with 451 gallons of gasoline, charts, five sandwiches, and two canteens of water, departed from Roosevelt Field, Long Island, New York, intent on claiming the $25,000 Orteig Prize by flying non-stop across the Atlantic to Paris, France. Lindbergh touched down thirty-three and a half hours later at Le Bourget Aerodrome outside of Paris, May 21, at 10:22 pm, local time.

    One week before his flight, with media attention reaching its crescendo, Lindbergh was introduced to Richard "Dick" Blythe, himself a pilot and co-owner of the public relations firm, Bruno and Blythe. Blythe represented Wright Aeronautical, the company which built the J-5C Whirlwind engine for the Spirit. From that moment, at the suggestion of Wright Aeronautical, Bruno and Blythe would handle the press, relieving some of the pressure Lindbergh was beginning to feel. Blythe became Lindbergh's agent and the two forged a lasting friendship. Lindbergh gave Blythe his daylight/darkness chart, in apparent appreciation and as a memento of his flight, to which Blythe has written on the back: "Captain Chas. A Lindbergh/daylight and darkness chart/May 1927." In the opening years of the Second World War, Richard R. Blythe returned to his native Canada to train pilots for the Royal Canadian Air Force and was tragically killed in 1941 during a training accident. Lots 34218 - 34234 are from the Richard Blythe Aviation Collection. There are additional lots in Session 2 of this auction. From the Richard Blythe Aviation Collection.
