RIO DE JANEIRO (AP) — A small, unmanned hot-air balloon has crashed into the roof of one of the areas in Rio's Olympic Park, causing minor fire and water damage but with no reported injuries.
Rio organizing committee spokesman Mario Andrada says the balloon was probably launched from one of the city's favelas and hit the Carioca 3 Arena. Andrada says "firefighters used a lot of water, and water spilled into the field of play."
The balloon struck early Monday morning. Officials were able to repair the limited damage, which allowed a wheelchair fencing event to start on time.
