I recently learned (Toto pulled the curtain back) a fire service member that contributed a great deal to one of the most popular fire service training manuals has never actually fought a fire outside of a ConEx box (metal fire training building). So does that mean that we need to question the credibility of the editors? The answer is YES. Trust but verify seems to be the way to go.
