Editing Verneshot (section)

== Tunguska event ==
A verneshot has been proposed as an alternate explanation for the [[Tunguska event]], widely regarded as the result of an atmospheric explosion of a small comet or asteroid. Arguments offered for this mechanism include the lack of extraterrestrial material at the event site, the lack of a credible impact structure, and the presence of shocked quartz in surface outcrops.<ref>{{cite journal |last1=Vannucchi |first1=Paola |last2=Morgan |first2=Jason P. |last3=Della Lunga |first3=Damiano |last4=Andronicos |first4=Christopher L. |last5=Morgan |first5=W.
