Robert Wood 2004 Planetary Defense Conference: Protecting Earth from Asteroids; Orange County, CA; Feb. 23-26, 2004 On October 8, 1871, a fire started that burned much of Chicago, killing 300, and destroying $200,000,000 worth of property. Most people are unaware that within a few minutes, major fires started in upstate Wisconsin and Michigan, killing more than 2000 people in the farming country.

It has been hypothesized that one of them struck Earth and broke into several smaller pieces. These pieces, consisting of frozen comet gases would have likely included combustibles like methane CH4 and acetylene C2H2 that melted, vaporized and explosively ignited, causing impressive incendiary results upstate, consistent with surviving witness reports. A two dimensional evaluation by the author of the orbit of Bielas Comets two parts shows that it
