The balloon was passing over Bristol as part of the city’s International Balloon Fiesta, and was spotted flying low before hitting the roof of Oasis Academy Connaught, Knowle West, close to the scheduled landing site, on Friday, August 8, at 7.11am.
The balloon basket was seen tipping as they tried to get back into the air and it “looked like the people were going to fall out”.
The balloon was able to recover and rise again up and over the roof of the school.
Resident Stephanie, 22, a lash technician, who captured the moment said: “I thought ‘that one is looking a bit low’ and pressed record.
“The basket was tilting – it looked like they were going to fall out.
“It must have been scary.
A spokesperson for the Bristol International Balloon Fiesta, said: “During this morning’s incredible mass ascent of 90 hot air balloons, one of the balloons clipped a roof as it was coming into land.
“Everyone landed safely, and we are looking forward to a brilliant Fiesta weekend.”
