Aviation Accident Summary CHI98LA184

WATERLOO, IA, USA

Aircraft #1

N25491

Balloon Works FIREFLY 7-15

Analysis

The accident balloon was part of a balloon rally. The pilot reported that he arrived at the target drop area near the Waterloo Municipal Airport. He further reported that 'After throwing my baggie I started to burn to get enough lift to clear powerlines. It seems to me we were going parallel with the powerlines along Jordan Street and would have cleared the powerlines on West Airline Highway when a gust of wind took us into the powerlines on Jordan Street.' After contacting the wires the balloon slid horizontally down the wires until the basket came to rest alongside a power pole. The pilot secured the basket to the pole using a rope and waited for approximately 2 hours until he and the passenger were lowered out of the basket by the fire department. Calm winds were reported in the area at the time of the accident.
