There was a time in the United States when you could hop into a carriage pulled by ostriches—yes, ostriches! In the late 19th century, entrepreneurs in California and Florida tried to make these speedy birds a tourist attraction, offering everything from carriage rides to ostrich races and extravagant feathered fashion. But why did this quirky tradition disappear? In this video, we dive into the rise and fall of ostrich taxis and how they went from a strange fad to a nearly forgotten piece of American history.

The Park Avenue Tunnel in New York City, also known as the Murray Hill Tunnel, is a historic underground passage originally built in the 1830s to carry the New York and Harlem Railroad. Initially an open cut, it was enclosed in 1850, creating a tunnel that ran under what is now Park Avenue between 33rd and 40th Streets. The tunnel allowed trains to access Grand Central Depot, the predecessor to Grand Central Terminal, but in 1872, passenger train use was stopped south of the depot due to noise and safety concerns. In 1913, following the completion of Grand Central Terminal and the electrification of trains, the tunnel was repurposed for automobile traffic, making it one of the city’s unique thoroughfares for vehicles. Today, the Park Avenue Tunnel is occasionally used for art installations and remains a testament to New York’s evolving transportation infrastructure.

The tunnels beneath Los Angeles, spanning over 11 miles, are a largely forgotten network that dates back to the early 20th century. Originally, some of these tunnels served as streetcar routes, connecting commuters across the growing city during the heyday of LA’s public transit system. Other tunnels were built to link civic buildings, facilitating the discreet movement of prisoners, officials, and even money between courthouses, jails, and banks. During Prohibition in the 1920s, these tunnels became infamous as secret passageways for bootleggers transporting illegal alcohol to speakeasies, with entrances hidden in bars and basements throughout downtown. While the tunnel network has since fallen into disuse, it remains a fascinating relic of Los Angeles’ layered history, hidden just below the bustling streets.

In the 1940s and 1950s, Chicago was home to an experimental helicopter airway system, part of an effort to integrate helicopters into urban air transport. The system, known as the "Chicago Helicopter Airways," operated along designated flight paths that hovered above the city's lakefront and major highways, aiming to connect downtown with airports and suburban areas. It became one of the few helicopter services in the U.S. to establish a scheduled passenger route. However, high operational costs, limited passenger demand, and the emergence of more efficient transportation modes led to its decline by the late 1960s, ultimately leaving the ambitious project as a forgotten chapter in Chicago’s aviation history.

The Alfred P. Murrah Federal Building, completed in 1977, was a prominent structure in downtown Oklahoma City, housing numerous federal offices, including the Social Security Administration and the Secret Service. Tragically, on April 19, 1995, it became the site of one of the deadliest domestic terrorist attacks in U.S. history when a truck bomb, detonated by Timothy McVeigh, killed 168 people and injured over 600. The bombing not only devastated the building but also profoundly impacted the nation, leading to increased security measures and a national conversation about domestic terrorism. Today, the site is home to the Oklahoma City National Memorial, honoring the lives lost and promoting healing and remembrance.

In this episode, we dive deep into the forgotten ruins of Minneapolis, uncovering the remnants of a city’s untold history. From abandoned structures to hidden landmarks, discover what was left behind and the stories that still echo through these lost spaces. Join us as we explore the past and piece together a forgotten chapter of urban decay and transformation.

At the height of the Cold War, as the United States and the Soviet Union vied for control of the seas, the USS Plainview (AGEH-1) emerged—a hydrofoil ship promising to revolutionize naval warfare. Capable of "flying" over the water, its groundbreaking technology set high expectations, but its journey was filled with unexpected challenges. Was the Plainview a failure or a precursor to the modern innovations in naval engineering? Uncover the intriguing story of the ship that could fly but never entirely fulfilled its true destiny.

The Abandoned Westinghouse Atom Smasher, located in Forest Hills, Pennsylvania, was part of a groundbreaking effort in nuclear physics during the 1950s. Originally built by the Westinghouse Electric Corporation, the facility housed a particle accelerator that was instrumental in advancing research on atomic and subatomic particles. However, by the late 1970s, as funding for nuclear research diminished and safety concerns increased, the atom smasher was left to decay. Despite its abandonment, the site has become a point of interest for urban explorers and historians, highlighting both the ambitions of mid-20th-century science and the complex legacy of nuclear technology. Today, remnants of the structure serve as a reminder of a pivotal era in scientific exploration, marked by both innovation and caution.
