'Glass worms 1' (The Enterprise Mission) with the Haisch and Pieri e-mails

Enterprise Mission PDF shown on Reality Check (47:35). It reproduces e-mails from Bernard Haisch and David C. Pieri and a reply by geologist Ron Nicks. Haisch's e-mail opens: 'Hal Puthoff asked the following. What do you know about this image?' Haisch called it the biggest technical laugh he'd had in weeks and mocked the Clarke quote. The Enterprise side argues the sand-dune reading ignores how real structures vary in spacing and depth.
