The director of the Bristol International Balloon Fiesta has explained why the evening mass ascents have had to be called off on the first two days of this year's festival.
Speaking to the crowds at Ashton Court this morning (Saturday, August 13) ahead of another successful morning mass ascent, Clive Bailey explained the rare weather conditions that have kept the balloons tethered in the evenings so far.
Thursday and Friday's mass ascents were called off at around 6pm, with the ground temperature on the balloon field still up around 31 degrees, and barely a breath of wind being felt by the thousands who have come to the fiesta. But it's the conditions up in the air that is the issue for balloon pilots, Mr Bailey said.
