Karl Bacon, co-founder of Arrow passes away.
You might not know the name, but you've certainly experienced his genius - Matterhorn Bobsleds, virtually every dark ride in Fantasyland, Pirates of the Caribbean - all featuring ride systems created by Karl Bacon and Ed Morgan. Bob Gurr designed the Autopia cars, Karl and Ed designed the system for the single rail guide.
If you get a chance, check out the book "Rollercoasters, Flumes and Flying Saucers" - there's some great construction pics of old Disneyland favorites, it's amazing what these two contributed.
