While colourful balloons were inflated in the main arena and aircraft whizzed past overhead, in a green tent on the edge of the fiesta site an army of volunteers was treating people for a range of injuries and illnesses.
For most people the Bristol International Balloon Fiesta is about the balloons and other aircraft, or the stalls and fairground rides, but the 110-strong team of British Red Cross volunteers were there to treat the minor ailments of those enjoying their day.
Pregnant Dawn Carter, of Burnham-on-Sea in Somerset, required the services of the medical team after she became dizzy and faint.
The 26-year-old had been waiting to watch the Great Western Air Ambulance take off from the arena when a member of the helicopter service came to her assistance before handing her over to the Red Cross team to be checked over.
"I got sat down and then the air ambulance person from the helicopter came out," she said.
"He handed me over to these guys who brought me over to their tent to monitor my blood pressure, glucose and oxygen levels and gave me water and pretty much just gave me some reassurance and advice."
The team dealt with almost 100 people suffering from headaches or dehydration as a result of the heat, 50 bee stings, 30 sprains and strains and ten people suffering with hay fever.
Fiona Gundry, volunteer support co-ordinator, said that the events the Red Cross cover are quite diverse, with volunteers in the local area helping out with Badminton Horse Trials and the Womad music festival.
The 35-year-old started working with the organisers of the balloon fiesta about a year ago to prepare her volunteers for this weekend's event.
While most of the volunteers for the event came from Avon, Gloucestershire and Wiltshire to help out, one couple came down from Lancashire and camped at Ashton Court Estate so they could support the Red Cross.
Andrea Mills is a headteacher, but during the balloon fiesta she was the British Red Cross medical centre's team leader, organising all the other volunteers. She has been volunteering with the charity for three and a half years.
"With the larger events it is all about the team work and the camaraderie of working with other people," Andrea said.
"We have fantastic volunteers from all over the country coming to the large events and there is a real sense that everyone wants to do their best.
"They want to help and that is why they are in the Red Cross."
