Perhaps we should take these off for now? per @choldgraf

Before we remove them we should spend a moment trying to debug why they don't work or replace them with this launch success plot. I find the plot I linked much easier to interpret so I'd be 👍 for replacing.

I wouldn't mind replacing them with the launch success plot for now.
