ImplosionWorld has issued some clarifications and now their paper is available at a new link:

• Steven E. Jones apparently does not have a doctorate degree, so Implosion World changed the text to refer to him as “Professor Jones”
• They also clarify what they mean by “pancaking” - don’t take the term too literally! The term is meant as a general visual description to help readers understand the more advanced concepts.
• ImplosionWorld also updates about their portable seismographs, saying that because these are far less technologically advanded, they can’t be taken on their own as evidence. To supplement this, they refer to Columbia University seismograph readings, which they interpret “clearly indicate explosives were not used”.
