Lower shock trox bolt size. I plan on replacing the rear shocks on my 2015 FXDL with the emulsion shocks. The lower shock bolt has a trox head & I will need to buy a trox socket to do the replacement. Could you tell what size trox socket I will need & if it is a tamper-proof type or regular type.
Not until 1909 did the Signal Corps purchase an aircraft for military purposes. The U.S. Navy purchased its first plane, a derivative of the Curtiss Golden Flyer, in July 1911. On March 31, 1911, Congress first appropriated funds for military aviation, $125,000.
Gustave Whitehead invented and flew the  world's first airplane in 1901, at Fairfield, CT. His monoplane,  called No. 21 or the Condor, was based on Count D'Esterno's and  Otto Lilienthal's designs.
