Phil Silvia has fowarded a link to an update of the article first published a few years ago – now withdrawn. It is now published by Science Open …
https://www.scienceopen.com/hosted-document?doi=10.14293/ACI.2025.0003 …
It is also available in a paper edition in the journal ‘Airbursts and Cratering Impacts‘ … and they have some other interesting articles in the same volume.
I shall do another post on this when I have fully read the article but it seems to have added a lot of additional information to the original article, especially where it concerns the fragments of human bone in the destruction layer.
