Howard DGA-6 Mister Mulligan
In 1933, Benjamin Odell Howard, a pilot for United Air Lines, decided that he wanted to get into the corporate-airplane business. To do it, he chose to design and build a fast four-place machine to win the Bendix Trophy cross-country race. This would both bring the plane instant notoriety and give him prize money to help defray the cost of development. He enlisted the help of a promising young engineer named Gordon Israel in designing Mister Mulligan, a high-wing, strut-braced cabin monoplane. Benny Howard had discovered the magic of supercharging and high-altitude flight. In 1935, he and Israel flew Mister Mulligan at 20,000 feet and above from Los Angeles to Cleveland and won the Bendix race at an average speed of 238.7 mph.
With DGA-6 Mister Mulligan Howard won all three major American racing titles in 1935, and this design was developed through several models into the Howard DGA-15.
