Sky 90-24, G-VINO
The pilot and three passengers departed a large open playing field area on the east side of the village of Mytholmroyd for a one hour pleasure flight. The balloon was climbed to 2,000 feet and tracked in a westerly direction. The weather was good with the 1,000 feet forecast wind from 090°/09 kt and CAVOK. The flight was uneventful and after one hour the pilot selected a landing site in a field at the top of a steep sided valley. The balloon passed over the valley and the wooded upslope towards the landing site touching down in virtually calm wind conditions. The envelope however, collapsed quickly on top of the basket and burners due to the downdraft created by the wind passing over the trees and valley upslope, upwind of the balloon. A flying wire contacted the burner gas supply control lever, briefly opening it and releasing propane gas which was ignited by the pilot lights. A ball of flame passed under the collapsed envelope singing the hair and causing a minor burn to the face of one of the passengers.
