The tunnel thru the air
Looking back from 1940
William D. (William Delbert) Gann (1878–1955)
This narrative serves as a speculative blueprint for the future, blending a young man’s romantic devotion with his rise as an inventor during a global conflict that mirrors biblical prophecy. It presents a vision where personal discipline and spiritual alignment lead to technological mastery and ultimate peace.
In Short
This book is a unique hybrid of romantic fiction, biblical exegesis, and early twentieth-century science fiction. It follows Robert Gordon, a young genius whose unrequited love and diligent study of the Bible lead him to predict future wars and invent revolutionary defensive technologies. By grounding his personal success in faith and his scientific breakthroughs in scriptural cycles, the author creates a idiosyncratic vision of the year 1940. It has endured as a cult object for those interested in the intersections of market speculation, prophetic mysticism, and the mechanical optimism of the 1920s.
The Story
Robert Gordon, a young man of profound intelligence, lives his life by the conviction that the Bible contains a scientific code capable of predicting historical cycles, stock market trends, and the dates of future wars. His life is defined by his deep, longing love for Marie Stanton, whom he views as his spiritual anchor. When Marie leaves him unexpectedly to pursue her own path, Robert channels his heartbreak into obsessive work. He applies his studies of the prophet Ezekiel to anticipate a great aerial war, eventually becoming a supreme military commander and inventor for the United States.
As the world descends into a massive conflict, Robert utilizes his understanding of natural laws to create "The Pocket Radio" and a mysterious device capable of creating a "Tunnel Thru the Air"—a defensive barrier that uses sleeping gas to neutralize enemy air armadas without loss of life. His tactical brilliance and his inventions turn the tide of the war, saving the United States from an alliance of foreign powers. Despite having the power to annihilate his enemies, Robert chooses the path of mercy, inspired by his belief that love and forgiveness are the highest forms of power.
Throughout his rise to fame, Robert never loses hope that he will be reunited with Marie. He views his suffering and his inventions as part of a divine plan, believing that his discipline has been rewarded by God. The climax occurs as the war concludes; Robert is hailed as a savior and a prince of peace. In a final, transformative scene, his comrade reveals that Marie has been kept safe through divine providence. The two are reunited, and the story concludes with the promise of their marriage and the establishment of a new global order centered on the "City of the Lord," marking the beginning of a peaceful era where the laws of love supersede the brutality of human conflict.
How It Unfolds
The call of the cycle Robert begins as a young clerk whose life is reshaped by illness and the study of scripture. He deduces that biblical prophecy is a scientific map, signaling that 1927 will bring floods and that a massive war will soon consume the world.
The invention of necessity Driven by his need to protect his country and his desire to prove his worth, Robert perfects his secret inventions. He successfully tests a miniature radio device and works in isolation to build a formidable, silent aircraft, all while predicting stock market shifts with uncanny accuracy.
The descent into chaos The war begins, and Robert moves from the fringes of industry to the center of the military effort. He faces setbacks and captures enemy technology, eventually finding himself at the helm of the United States' defense against a coalition of global powers.
The final confrontation As enemy forces gather for a final, decisive assault on New York, Robert deploys his "Tunnel Thru the Air." He achieves victory not through destruction, but through a compassionate, bloodless display of overwhelming technical superiority.
The reunion With the world saved and the principles of mercy established, Robert’s long wait ends. He is reunited with Marie, his personal "pearl of great price," confirming his faith that love is the ultimate reward for a life lived according to divine law.
The People
Robert Gordon is the book’s central figure, a man of intense focus and romantic idealism. He wants both personal happiness with Marie and the success of his country, but he is constantly thwarted by external forces and his own internal longing. He evolves from a lovestruck youth into a messianic military leader.
Marie Stanton is the catalyst for Robert’s transformation. Her presence in his life—and her mysterious absence—drives his ambition and keeps his heart anchored in faith. She represents the "pearl of great price," and her eventual return validates Robert’s lifelong commitment to patient, unselfish love.
Mr. Kennelworth acts as a mentor and benefactor to Robert, providing the capital and support necessary for Robert to develop his inventions. He serves as an audience for Robert’s theories, grounding the more esoteric passages in the practical world of business and finance.
In Its Own Voice
"The 'Tunnel Thru the Air' is mysterious and contains a valuable secret, clothed in veiled language."
This assertion in the foreword establishes the author’s intent for the book to be read as a multi-layered puzzle rather than a straightforward narrative.
"He realized that Ezekiel's prophecy of that war which was to come and be fought in the air, was coming true, and the great plane described by Ezekiel, the eagle with wheel within a wheel, would one day become a reality."
Robert interprets ancient scripture as a literal, technical forecast of future military aviation.
"He knew that the noisome beasts were the airplanes, and that all of these things had happened."
Robert reflects on the aftermath of the conflict, framing modern warfare through the symbolic lens of biblical terror.
What It's Really About
At its core, the book argues that history is not random but follows a repeating, predictable cycle defined by divine law. It posits that science and faith are not contradictory, but two sides of the same coin; true understanding of one allows a person to master the other. The text suggests that the highest human achievement is not technical progress, but the realization that love is a tangible, governing force. It is a treatise on the power of "foreknowledge" and "preparedness," suggesting that if a man aligns his will with the patterns established in the Bible, he can transcend the limitations of his time to achieve both material success and spiritual enlightenment.
Why Read It Today
This book appeals to those fascinated by the odd corners of literary history and the minds of visionary eccentrics. It is less a traditional novel and more a dense, idiosyncratic manifesto that reads like a dream of the future filtered through the perspective of a 1920s stock analyst. Readers should be prepared for its unconventional structure; the narrative often pauses for long stretches of biblical analysis, historical data, and stock market philosophy.
The prose is earnest and urgent, reflecting the era’s burgeoning obsession with aviation and the radio. While modern readers might find the period-specific attitudes toward gender and the sometimes repetitive, preachy nature of the dialogue challenging, those who enjoy untangling complex, cryptic systems will find much to ponder. It feels like stepping into a private, hermetic world where the Bible is an engineering manual and the heart’s desire is the fuel for global salvation. What stays with you is not the plot, but the sheer, defiant confidence of the author’s belief that everything—from the fluctuation of cotton prices to the trajectory of a world war—can be mastered by a mind that understands the hidden rhythm of the ages.
