Moment hot air balloon crash lands on the roof of a primary school

Moment hot air balloon crash lands on the roof of a primary school during an international festival. Shocking images show the balloon flying low before it hits the roof of Oasis Academy Connaught in the Knowle West area of the city. Witnesses described seeing the basket tipping as it tried to get back into the air and how it 'looked like the people were going to fall out'.
