they were so far behind the leader. As a result they returned to Chicago on July 22nd and remained there [strikethrough] until [/strikethrough] into August, carrying [strikethrough] social [/strikethrough] passengers and demonstrating the "Aeroyacht".

Back in California, Day evidently remained with Martin through 1913. That winter, he left again to design and build a special exhibition tractor biplane using a 50 [strikethrough] H.P. [/strikethrough] Gnome engine for DeLloyd Thompson. This plane was flying at Los Angeles in March, 1914, and Thompson began looping it. In May, Day and Thompson returned to Chicago with this machine, where apparently Day was mechanic and assistant to Thompson in exhibition flying. By July they had installed an 80 [strikethrough] H.P. [/strikethrough] Gyro engine in the plane and were at Overland Park, Kansas City, Missouri, on an extended exhibition engagement. Well known Chicago aviation mechanic Al Hofer was also with them and preparations were under way for an attempt at an altitude record flight. On August 6th Thompson did set a new United States altitude record of 15,580 feet [strikethrough] there [/strikethrough] with his plane. While on this assignment Thompson reportedly gave Day more instruction and he became a very competent pilot. 

In September Day became Chief Engineer of the Aircraft Company, Inc. of New York, a new firm which ad just been formed due to a reorganization of the Sloane Airplane Company. The new firm had shop facilities in Long Island City, New York, and Boundbrook, New Jersey. On May 5 [strikethrough] th [/strikethrough], 1915, Day became a member of the Aero Club of America. In this new capacity during the remainder of 1915 Day engineered a new Sloane-Day training type, [strikethrough] a [/strikethrough] tandem tractor biplane with a 90 [strikethrough] H.P. [/strikethrough] Kirkham engine. He made special exhibition machines for DeLloyd Thompson and Overton Bounds, and a new Model H, 40-foot-span military tractor biplane with a 6-cylinder 125 [strikethrough] H.P. [/strikethrough] Hall-Scott engine. As the year ended, Day was in Great Britain with the new Model H machine and came home with an order.

On April 10 [strikethrough] th [/strikethrough], 1916, DeLloyd Thompson established a new American altitude record of 13,950 feet for pilot and [strikethrough] a [/strikethrough] passenger at Garden City, Long Island, flying a Sloane-Day Model H Plane. After another re-organization of the Aircraft Company [strikethrough] firm was made [/strikethrough] in mid-May,[strikethrough] when [/strikethrough] John Sloane retired and the name changed to Standard Aero Company. Day was now Vice-President and Director of Engineering. Standard soon received a United States
