Charles Healy Day joined as designer in 1914, later becoming chief engineer and designer. Day had worked as a designer for the Glenn L. Martin Co. in 1911 and 1913 and had managed his own tractor biplane shop 1912-mid 1913. Firm called Sloane Aeroplane Co. by SD at 95 and 215 and Sloane Aircraft Co. at 264; called Sloan Aircraft Co. by G282 and 2dG430. According to Aeronautics, Dec 1911, Sloane Aeroplane Co., 1777 Broadway, NY, was new firm started by J. E. Sloane, South Orange, NJ, and A. A. and H. Vantine of New York City. Between then and 1919, some media alternatively referred to the firm as Sloane Manufacturing Co. or Sloane Aeroplane Manufacturing Co; others said Sloane Aeroplane was the successor to Sloane Manufacturing. A. A. Vantine Co. was an established importer and seller of goods from the Orient ; its connection to Sloane Aeroplane Co. is not known.

Sloan advert in Aircraft magazine, March 1913. "National Aeroplane Company, 606 South Michigan Avenue, Chicago, Ill." is written in small type below. Was it the parent company?

Manufactured four designs that were, in sequence, a scout monoplane, a flying boat, a military tractor biplane, and an exhibition tractor biplane, before it started its H series in 1916; the H series included two types of tractor biplanes, a reconnaissance biplane, and a trainer, that were built in small numbers for the U.S. Army. In 1912, which was prior its manufacturing, operated a flying school using Deperdussin monoplanes. In 1915, it opened a flying-boat school; also, in 1915, it had a team of exhibition aviators. At various times, it professed to represent the Charavay propeller, Deperdussin aeroplanes, the Smith Tachometer, and Anazani and Le Rhone in the U.S. On 12 May 1916, Sloane Aeroplane Co. was taken over involuntarily by the newly-formed Standard Aero Corp., which had possession of a majority of Sloane Aeroplane Co.'s shares, and Sloane's assets became the nucleus of Standard Aero Corp.

The NY Times, 1 May 1917, revealed that John Sloane, who held 26,500 of the 50,000 shares in Sloane Manufacturing Co., had provided his shares as collateral to the Mitsui Co., the large Japanese banking conglomerate, in order to borrow funds from them to finance the manufacture of aeroplanes for the Russian government. Sloane alleged that Mitsui, rather than waiting to be repaid from the profits of this venture, transferred Sloane's stock shares to Standard Aero Corp., which then stripped the Sloane Co. of its assets and business. Mitsui contended that after Sloane had borrowed funds from Mitsui and been unable to repay the loan, Sloane had adjusted the matter by turning over his stock in payment. For the connection of Mitsui to Standard Aero Corp., see the first entry on Standard Aero Corp.

According to the advertisement at right, Sloane Co. operated a flying school at Dominguez Field.

Corporation registered New York City, NY; flying school, Hempstead Plains, Long Island, NY; flying boat school,.Larchmont, NY; initial factory at Bound Brook, NJ; later, factory was in Plainfield, NJ.
