On September 26, 2024, an extraordinary incident occurred in the Brazilian suburb of Osasco, part of the São Paulo metropolitan area: an ADB 3-3 airship crashed into a residential building.
Fortunately, there were no fatalities, but the accident raises questions about the safety and reliability of airships. The incident occurred during a promotional flight for the football club São Paulo FC, which had rented the airship for an event surrounding a Copa Libertadores match.
An unexpected crash
Around noon local time, the airship began to lose altitude rapidly over the Osasco district. According to eyewitness accounts and videos posted on social media, it seemed as if the airship lost air without warning and spiraled uncontrollably towards the ground. It eventually crashed into the facade of a residential building. Fortunately, only the pilot and co-pilot were on board at the time of the accident, and both were rescued by the rapid deployment of rescue services. Both suffered only minor injuries, which can be attributed to the relatively slow speed of the airship and the relatively gentle nature of the collision.
The airship involved, a model of the ADB 3-3 series, was manufactured by Airship do Brasil, a subsidiary of the Brazilian company Bertolini Enterprises. It is 49 metres long, 17 metres high and can reach speeds of up to 85 km/h. It was specifically designed for passenger and advertising flights and can carry a maximum of seven people (five passengers and two crew members). However, at the time of the accident, the airship was on a test flight for a planned night-time advertising campaign in which it was to fly over the São Paulo stadium, which was hosting an important football match between São Paulo FC and Botafogo that evening.
Repeating a successful event
For São Paulo FC, the use of an airship was not a first. A similar flight was already carried out in 2023 without incident. Airships are often used for large-scale advertising campaigns because their size and ability to hover slowly and conspicuously over certain areas make them ideal for advertising messages. The planned flight over the stadium was intended to showcase the football club's brand and sponsors by having the airship frame the football match with an illuminated banner.
São Paulo FC had specifically rented the airship for the Copa Libertadores match, one of the most important tournaments in South American football. The incident was a major setback for the club, which had been preparing for a spectacular presentation of its brand.
Investigating the causes: The role of the Brazilian aviation authority
After the crash, the Brazilian Aviation Authority (ANAC - Agência Nacional de Aviação Civil) immediately launched an investigation to determine the exact causes of the accident. Initial reports indicate that there were no external factors, such as mechanical malfunctions or adverse weather conditions, that could have directly caused the crash. Eyewitnesses report that the airship lost air abruptly, suggesting a possible technical defect.
Airships are generally considered to be safe means of transport and advertising, although they are used less frequently than other aircraft due to their complexity in control and their vulnerability to external influences. However, they continue to be used, particularly in advertising, due to their conspicuous presence. A similar incident in recent history occurred in 2017, when an airship crashed near the US Open Golf Championship. In this case, too, there were no fatalities, but the accident led to extensive safety reviews in the industry.
“Airship do Brasil” under pressure
The crash has caused major damage to the image of the manufacturer "Airship do Brasil", a subsidiary of Bertolini Enterprises. The company is one of the few remaining manufacturers of airships in Brazil and specializes in the construction of modern, lightweight models for civil and commercial purposes. The ADB 3-3 series is one of the company's flagships and was originally developed to be used for both tourist flights and promotional purposes.
However, the incident now poses a challenge for the company, particularly with regard to future contracts and partnerships. The results of the ongoing investigation by ANAC will largely determine how the company will act in the future. It remains to be seen whether the incident was due to a design defect or to individual circumstances during the flight.
The question of aviation security
This incident raises the question of how safe airships are in modern times. Airships, which played a significant role in air travel in the early 20th century, are now considered an exotic but rarely used mode of transport. Although they do not replace high-speed aircraft, they offer unique advantages in the field of advertising and in specialized transport tasks, such as flying over difficult-to-access areas.
Despite their relative safety compared to other aircraft, airships are prone to technical problems because they require a complex interaction of gas, structure and control. The fact that no one was seriously injured in the Osasco incident speaks volumes about the robust design of modern airships. Nevertheless, experts will closely monitor the results of the ANAC investigation to determine whether similar models will have to be subject to additional safety requirements in the future.
The Osasco airship crash is a wake-up call for the industry. While technological advances have made airships safer, operational safety remains of key importance. The results of the investigation could have far-reaching implications for the use of airships, particularly in densely populated areas. Even if the crash was minor, the question remains whether airships still have a future as advertising platforms in urban centers.
