One "problem" with Collins' book was with SLO's.
It was a comet which hit, and they do not contain much silica.
While a nuclear airburst can produce SLO's, not so for cometary airbursts - the energy released is too low and the release occurs too high too high.
If you have SLO's, most likely they are from ground impact.
Either that, or you have tangential impact, or multiple air impacts with intense fire, and I'm not real sure about the last as an SLO production mechanism.
We'll see- the distribution of impactites will lead to localization.

Usually people believe what they want to believe until reality intrudes.
