The Albuquerque International Balloon Fiesta had its first lift off in 1972.
This year's event saw over 500 balloons from nearly 20 different countries glide across the New Mexican sky.
The festival is held in Albuquerque due to a wind pattern known as "the box" that makes it easier to navigate the giant balloons.
"When dreams take flight" was the theme of this year's event, which ran from October 3 to 11.

The first festival featured a fleet of just 14 balloons.
Today, balloonists from South Africa to Thailand make the trek to Albuquerque to be part of the magic.
The event attracts hundreds of thousands of spectators.
Local vendors selling food and souvenirs depend on the festival's tourist draw.

Due to the weather, some of the balloons were inflated but never lifted off.
There have been a few harmful and fatal accidents among balloonists over the years.
Between 1990 and 2007, six people died when their balloons hit power lines. And in 2013, two men were badly injured after their vessel hit a power line and sent them crashing down.
No injuries were reported this year. Pilots now have access to a new radar system and are better informed of wind patterns, according to the festival's executive director.
