Curtiss airplane of the day, but with four Farman-type ailerons mounted flush to the end of all four wings replacing the Curtiss-style ailerons normally located between the upper and lower wing. The upper and lower ailerons were connected to each other via a vertical pole and operated in unison. They were moved via wires connected to the pilots steering wheel post. The wings also had about 1/3 more surface area than a Curtiss, spanning 40 feet with a 4.5 foot chord. It measured 37 feet from the tip of the forward elevator to the tail of the rudder. Both the rudder and front elevator were double surfaced, or box-type, with the rudder being enclosed by a pair of two foot square vertical wings on either side of the horizontal surface. There was no elevator function to the tail. The tail and elevator surfaces measured approximately two feet by six feet and were set much farther out from the wings than a normal Curtiss. Unlike the Harkness airplane, however, this Silver Dart was powered by the first production 40 hp, four-cylinder Hall-Scott engine which turned an eight-foot propeller. Exhibition aviator Pacific Aviation Company Walsh began his career as a professional exhibition aviator with the Pacific Aviation Company, owned by the Manning Brothers of Portland, Oregon. His first event was May 11–12, 1911 in Roseburg, Oregon. He kept a very busy schedule throughout the Pacific Northwest and endured some close calls and crashes. At his event at Laramie, Wyoming, on July 31, he set a record for the highest elevation at which airplane flight was ever successfully conducted in the United States (7200 feet). While Alice Walsh would later recall that Charles had his Silver Dart stolen at Kearney, Nebraska, about a week later by the Manning Brothers, this account is disputed by local newspapers. His airplane was reportedly almost completely destroyed when he hit a tree during his exhibition there on August 4. Following that, on August 12, Charles Walsh landed in a cornfield while performing an exhibition at Fremont, Nebraska. The locals were very upset by what they considered a poor showing by Walsh. The farmer who owned the field sued the Pacific Aviation Company a few days later for $100 in damages to his crops and a local judge confiscated the airplane pending a settlement. This was perhaps the first such lawsuit of its kind. On August 24, the
