Sept. 30 – On this day in Montana history in 1911 young aviator Cromwell Dixon in a Curtiss biplane crossed the main range of the Rocky Mountains for the first time in history. He had left from the fairgrounds in Helena. He flew to Blossburg in half an hour and delivered a message from Gov. Edwin Norris to the crowd there that stated that its delivery was the proof of the record setting event. Air mail came later, but this might have been one of the first air mail deliveries.
