‑ ‑ NOTE: The "Then and Now" pages above are the results of investigations into just "where did it happen?" I find a photo of an item of interest, such as an airship over some city, and I attempt to identify where it was taken! Using modern tools like Google Earth, SketchUp, ScreenRuler, trigonometry, and available evidence I ferret out the location. Some really interesting things come up! If you have not checked out this site in a while, there's always new info added, and I've included several pages of Zeppelin memorials, monuments, and grave-sites as they become known to me.

"Is the Earth Flat?... Let’s Actually Test It!" - Original posting 29 Nov, 2020
This long page explains how to prove if the Earth is flat or not. Many believe the Earth is flat so I present a very simple test anyone can do to prove it. This is a long read so enough detail could be provided so the proof can be understood but it relies only on simple algebra and trigonometry.
