Mick Burke Film Competition Introduced by John Ridgway Earlier this year viewers chose the winning film from three finalists: two Essex teenagers who filmed their school's expedition to the Himalayas; climbers who struggled up a live volcano in the Andes, where boulders the size of cars come bouncing by; and some young explorers who peered out from the jungley top of a tepui - one of the remote 'lost worlds' of South America.
