Ulm, Charles (1897-1934), an Australian aviator, helped to pioneer flying in Australia. During the late 1920's, he flew with fellow Australian Charles Kingsford Smith. They made a record-breaking flight around Australia in 10 days 5 1/2 hours in 1927. They made the first transpacific flight in 1928. In 1934, Ulm flew from Britain to Australia in a new record time of 6 days 17 hours 45 minutes. That same year, he also made the first official airmail flight between Australia and New Zealand.
