Attention is invited to an addition to the list of blogs maintained in the sidebar: Aviation Trivia of the Day. It is curated by J.P. Santiago who describes himself as, among other worthy things, an "Aviation Über Geek."
The blog is a compendium of delightful arcana and obscurities from the world of aviation. I expect it to be a substantial time-sink for me as I spelunk through its archives. If you, too, are an "aviation geek", I believe that you'll enjoy repeated visits.
