In December of 2015, Wayne Coste and Barbara Honegger debated the question of whether a large plane hit the Pentagon. They then responded to questions.
A survey was conducted of debate listeners as to who won the debate. This can be viewed here. A total of 26 responded: 20 thought Barbara had presented the best case, 3 thought Wayne had, and three were not sure.
