Occasionally, Fire Management Today publishes comments from readers on topics of concern, offering authors a chance to respond. Stephen A. Eckert contends that the 'Brewer fire mystery' is not so mysterious. He says that the conditions were ripe for extreme fire behavior, and that under those conditions, the fire quickly went from a surface fire to a running fire. Under the severe burning conditions at the time, what happened on the Brewer Fire is no mystery. Martin E. Alexander responds that Mr. Eckert missed the point as to what the 'mystery' for the blowup was. He says the real question is, what actually triggered the temporary escalation in extreme fire behavior on that particular evening in late June 1988? He speculates the theory that a heat burst (HB) was responsible for causing the blowup or flareup that forced the Wyoming Interagency Hotshot Crew (IHC) to move away from the fire to a clearing and deploy fire shelters.
