Today is April 7, 2026, and we’re diving into the intriguing history and recent developments surrounding the Dade-Collier Training and Transition Airport, located in the heart of the Florida Everglades, in unincorporated Collier County. This former public airport has a unique past that intertwines with environmental concerns and the evolving landscape of immigration policy.
Dade-Collier Training and Transition Airport (IATA: TNT, ICAO: KTNT, FAA LID: TNT) was initially launched in 1968 as the Everglades Jetport, also known as Big Cypress Jetport. It was ambitiously designed to be the largest airport in the world, sprawling over 39 square miles with plans for six runways. The airport, situated 36 miles west of downtown Miami, was meant to connect central Miami to the Gulf of Mexico through a proposed highway and monorail system. However, due to environmental issues and the cancellation of the Boeing 2707 program, construction stalled in 1970 after the completion of a 10,500-foot runway. The remaining land was ultimately designated as part of the Big Cypress National Preserve.
The Transition to Training and Detention
Throughout the 1970s, the airport found a second life as a training hub for airlines like Pan Am and Eastern Airlines. Its remote location allowed for undisturbed training flights around the clock, easing congestion at Miami International Airport. While the advent of flight simulators reduced the need for such extensive training facilities, the airport remains operational for general aviation.
As of October 10, 2018, the airport recorded 14,468 general aviation operations, averaging 39 per day, showcasing its ongoing relevance in the aviation sector. However, the site’s future took a sharp turn in July 2025 when the South Florida Detention Facility, informally dubbed “Alligator Alcatraz,” was established on the airport grounds as an immigration detention center.
On July 1, Governor Ron DeSantis announced the creation of this facility, which can accommodate up to 3,000 undocumented immigrants. Critics, including Democratic legislators, environmental groups, and the Miccosukee Tribe, have voiced strong opposition, citing insufficient environmental impact assessments. They argue that the project poses significant risks to local wildlife and the fragile ecosystem of the Everglades.
Controversies and Legal Challenges
The DeSantis Administration has defended the center as essential for supporting federal immigration enforcement efforts led by President Donald Trump. Following the construction announcement, a series of protests erupted, and environmental advocacy groups filed lawsuits seeking to halt the project until comprehensive environmental reviews were conducted. The legal battles escalated, with a federal judge issuing a temporary restraining order on August 21, 2025, prohibiting further detainee transfers or construction at the facility. However, this order was later stayed while appeals were pending.
As construction progressed, reports of poor conditions surfaced, with allegations of unsanitary facilities and inadequate medical care for detainees. Lawmakers were invited to tour the center, and conditions were described as harsh, leading to further outrage and legal actions. By July 25, the first deportation flights commenced from the facility, marking a new chapter in the use of the Dade-Collier site.
A Look Ahead
In addition to its role as a training airport and now a detention center, the Dade-Collier facility has also hosted high-speed automobile events and previously considered oil drilling on site, which was abandoned due to pushback from conservationist groups. Interestingly, the Carlos Gimenez administration proposed hosting a regular airshow at Dade-Collier, akin to the renowned Paris Air Show, which could further diversify the airport’s activities.
The Dade-Collier Training and Transition Airport’s journey reflects the complex interplay between aviation, environmental stewardship, and immigration policy in Florida. As we observe these developments, it remains vital to consider both the historical significance of this site and its potential future roles in our community.
