1. Square There is a business class turboprop airplane that often flies overhead to our larger regional airport that is well known for having propellers designed to create a square wave sound. Apparently it was designed by Ferrari and so it just had to have a distinctive sound, because the big ferrari crest on the tail, twin push props and a CANARD weren't attention getting enough...
