The cartoon is about something that was on a lot of front pages in September 1903: “the problem of aerial navigation.” Just below the picture, a little story about the impending voyage of Samuel Pierpont Langley’s flying machine Aerodrome is to be read as a footnote in advance.

Pedagogically, it teaches us that on October 7 and again on December 8, the Aerodrome and its pilot catapulted themselves into the air from a boat moored in the Potomac River but then nosed down and sank. Langley’s attempt at powered flight had been supported by the resources and publicity apparatus of the Smithsonian Institution, but when the ripples closed above them, the problem of aerial navigation remained unsolved.

It was to be solved on December 17 by Orville Wright, but even during the moment of the immediately post-Langley nobody at the Indianapolis Star was in position to see that coming. Elsewhere in its front-page layout for September 28 the Star had offered its subscribers opportunities to read about several murders, a gallows confession, an accidental electrocution, and a horse-show scandal. All those readings, however, were rooted in the still earth of September 1903.  The problem of aerial navigation remained as unsolved as ever. Column 1’s long article about a train falling from a trestle could treat only the idea of descent from ground to ground.

But the Wright Brothers solved the falling-body problem, and over the following years the solution became known. By 1924 the body at the foot of the trestle could be imagined on the rise. According to Wikipedia, this record of the change was the first country song to sell a million copies.

Listen to its cheerful whistlings. Fast mail train no. 97 had taken on feathered flesh. Now it could fly on to heaven, leaving its wood and metal mortalities in death-filled earth.
