Ed Yost own interests turned toward reviving the lost practice of manned hot-air ballooning. This technology had first been invented in France by in the late 18th century by pioneers led by the Montgolfier brothers, but under the Montgolfier system, the balloon's air was heated by a ground fire prior to the balloon being released. The inherent danger of this type of balloon flight led to the system being abandoned when hydrogen and later helium became available. One of Yost's key engineering insights was that a hot-air balloon could be made to carry its own fuel. The invention of relatively light burners
Gatineau Hot Air Balloon Festival the following years the festival became much larger and was one of the biggest festivals in Canada. Attendance at one point reached over 225,000 people and had over 150 balloons. In 1998, the festival was also hosting the World Hot Air Airship Championship, which was disputed by 16 teams from Europe, China and the United States. On July 14, 2001, Boileau who was the general manager since its beginning was involved in a horrific hot-air balloon accident just east of the Ottawa International Airport on Leitrim Road.
