Balloon expert: 'One of the safest forms of aviation'
It has been confirmed that two British tourists are among up to 19 people who have died in a hot air balloon crash in Egypt.
The balloon was flying over Egypt's ancient temple city of Luxor, around 300 miles south of the capital, Cairo.
It has been reported that there was a fire and an explosion before the balloon dropped a thousand feet into sugar cane fields.
Balloon safety expert Phillip Dunnington spoke to BBC News about what might have caused the accident.
