Beneath the streets of New York City lies a 27-mile pneumatic mail network that once transported 100,000 letters a day using air pressure. Operational from 1897 to 1953, this system shot steel canisters through underground tubes at speeds of 35 miles per hour, linking 23 post offices across Manhattan and Brooklyn. In this episode, we explore the rise and fall of New York’s pneumatic mail system, discussing its innovative features, ceremonial cat launches, same-day Wall Street contracts, disastrous tube explosions, and sandwich delivery mishaps. We also examine what remnants of this once-thriving system still exist today.

Pruitt-Igoe was a public housing complex in St. Louis, Missouri, built in the 1950s as part of a post-World War II urban renewal initiative aimed at providing affordable housing for low-income families. Designed by architect Minoru Yamasaki, the project included 33 high-rise buildings and was initially praised for its modernist design. However, by the 1970s, it faced significant challenges such as crime, poor maintenance, and inadequate community resources, leading to deteriorating living conditions. The complex was demolished starting in 1972, symbolizing the failures of mid-century urban planning and the ongoing socio-economic issues in urban America.
