Twenty-one hot air balloons rose up into the skies from the runway of Bristol International Airport early this morning to launch this year's Balloon Fiesta.

The colourful fleet of balloons ascended from the runway against a backdrop of landing lights and a glorious sunrise at 5am to launch the fiesta, which takes place between August 6 and 9.

Organisers said it was the first time in the airport's history that the runway had been used as a launchpad for hot air balloons.

People up early across the Bristol area this morning watched in awe as the balloons drifted from the airport along the A38 towards the city and landed in the Ashton Court area just after 6am, with one landing on a field next to the Long Ashton bypass.

The balloons were launched from the runway at 5am to ensure no disruption to flights was caused.

Event director Susan Tanner said: "We wanted to do something spectacular to honour this year's Fiesta.

"We were delighted to have Bristol International Airport on board to help us create such a magnificent and memorable sight."

The Bristol International Balloon Fiesta 2009, which takes place at the Ashton Court Estate, is expected to bring more than half a million visitors to the city.

The Red Arrows, the world's most famous aerobatic display team, will perform at the event, which will also feature mass launches of more than 100 balloons, two night glows where 30 balloons will light up the night sky in time to music, and a fireworks finale.
