The World Space Flight pages are anything BUT mobile friendly! That is a sad fact.
The good news is that that will be changing. The changes will be gradual, a few MAJOR changes coming first, followed by more general changes. The first big change which will be rolled out will involve the menus on the left side of practically every page.
As it is, you have to enlarge the area just to read it, much less actually click on something. America in Space already has the beginning of that change on MOST of the pages.
Once the menus have been adapted, then there will follow changes in the content layout. Be patient. Things will be getting better.
