The most photographed event in the world….

Tens of thousands of spectators swarmed the launch field Saturday for the first mass ascension of the 44th annual Albuquerque International Balloon Fiesta.

The nine-day event kicked off at dawn. More than 500 balloons representing dozens of states and nearly 20 different countries registered for the event this year. Among them were ‘Star Wars’ character balloons such as one depicting the head of  villain Darth Vader, which inevitably floated across from a Yoda balloon. Other popular draws included two bees kissing and a flying pig with sunglasses.

Organisers say it's one of the most photographed events in the world.

"Every time I turn around, I see another one," said Kim Kaiser, who came from Vermont. "I've got to get a picture of this one and that one."

One of the big draws of the balloon fiesta is the ability of spectators to roam the city's 72-acre  (29-hectare) balloon park to watch the morning mass ascensions.

Marilyn Oates, who traveled from Michigan, said nothing compares to being surrounded by so many hot air balloons.

"There's no explaining the majesty of it and it's so huge and you can't explain it in words," Oates said. "You have to come and see it."

A combination of factors makes Albuquerque the perfect place for the fiesta: typically clear skies, cool mornings and wind patterns at various elevations that help keep the balloons aloft over the city.

The mountains that border the city's east side and weather patterns help create what is known as the "box." When the box is in effect, the lower winds blow south and higher winds blow north, meaning balloonists can travel one direction, then backtrack to land near their launch site by changing elevation. That keeps the balloons bobbing over the city rather than drifting away.

Several balloons that took off in the morning later landed in a nearby park where balloon chase crews were poised to retrieve them.
