In the picture, he departs from this earth like an arrow. Although he has not chosen his fate, he appears to have, in his last instants of life, embraced it. If he were not falling, he might very well be flying. He appears relaxed, hurtling through the air. He appears comfortable in the grip of unimaginable motion. He does not appear intimidated by gravity’s divine suction or by what awaits him. His arms are by his side, only slightly outriggered. His left leg is bent at the knee, almost casually. His white shirt, or jacket, or frock, is billowing free of his black pants. His black high-tops are still on his feet. In all the other pictures, the people who did what he did — who jumped — appear to be struggling against horrific discrepancies of scale. They are made puny by the backdrop of the towers, which loom like colossi, and then by the event itself. Some of them are shirtless; their shoes fly off as they flail and fall; they look confused, as though trying to swim down the side of a mountain. The man in the picture, by contrast, is perfectly vertical, and so is in accord with the lines of the buildings behind him. He splits them, bisects them: Everything to the left of him in the picture is the North Tower; everything to the right, the South. Though oblivious to the geometric balance he has achieved, he is the essential element in the creation of a new flag, a banner composed entirely of steel bars shining in the sun. Some people who look at the picture see stoicism, willpower, a portrait of resignation; others see something else — something discordant and therefore terrible: freedom. There is something almost rebellious in the man’s posture, as though once faced with the inevitability of death, he decided to get on with it; as though he were a missile, a spear, bent on attaining his own end. He is, fifteen seconds past 9:41 a.m. EST, the moment the picture is taken, in the clutches of pure physics, accelerating at a rate of thirty-two feet per second squared. He will soon be traveling at upwards of 150 miles per hour, and he is upside down. In the picture, he is frozen; in his life outside the frame, he drops and keeps dropping until he disappears…

…But the only certainty we have is the certainty we had at the start: At fifteen seconds after 9:41 a.m., on September 11, 2001, a photographer named Richard Drew took a picture of a man falling through the sky — falling through time as well as through space. The picture went all around the world, and then disappeared, as if we willed it away. One of the most famous photographs in human history became an unmarked grave, and the man buried inside its frame — the Falling Man — became the Unknown Soldier in a war whose end we have not yet seen. Richard Drew’s photograph is all we know of him, and yet all we know of him becomes a measure of what we know of ourselves. The picture is his cenotaph, and like the monuments dedicated to the memory of unknown soldiers everywhere, it asks that we look at it, and make one simple acknowledgment.

That we have known who the Falling Man is all along.
