Update August 28th 2021: Last week Joomla 4, on which this site is running, was released. So I migrated, just to be ready for the future. But I wasn't prepared to say goodbye to the Beez template after so many years. Basic functionality works again, layout is still a shambles. Never mind, I'll keep working on it.
This year (2021) I have been working on the new website with a simpler setup. The goal is to make a large amount of digitized air racing information easily available to a large audience for a long period of time. Main factors are ease of storage, ease of retrieval and ease of maintenance.
Just to remind you of what the site looked like.
