the cabin. Despite many advancements, the flight instruments on the Ilya Muromets were primitive. They included four tachometers, one per engine, a compass, a crude altimeter and airspeed indicator, two glass U-shaped tubes and a ball for bank indication, and a series of horizontal bars situated vertically on the nose of the fuselage for measuring climbs and descents. Later, in the bomber variants, a drift indicator and elementary bombsight was added to aid bombing. In 1913 the Ilya Muromets No. 107 flew for the first time, and on 11 February 1914, the second prototype (factory airframe 128) took off for its first demonstration flight with 16 passengers aboard, marking a record for number of passengers carried. From 30 June to 12 July 1914, it set a world record by making a trip from Saint Petersburg to Kiev, a distance of some 1200 km, and back. The first leg took 14 hours and 38 minutes, with one landing for fuel at Orsha, and the return one, with a fuel stop at Novosokolniki, took even less time, about 13 hours. According to Sikorsky, "The flight proved conclusively the value of large multi-motored airplanes. The Army placed an order for ten four-engined airplanes of the Ilia Mourometz type and the factory personnel was overjoyed by this final approval of the results of two years of hard work." The acclaim received by Sikorsky included Tsar Nicholas II presenting him with the Order of St. Vladimir, Fourth Degree, arranging for an exemption from the wartime draft to allow him to continue his design work, and a promise of a grant worth 100,000 rubles from the State Duma. During an Imperial military review at Krasnoye Selo in July, Nicholas II decorated and christened the Ilya Muromets Type B Military Prototype, No. 128, the "Kievsky." During testing, the Ilya Muromets were fitted with both skis and pontoons in anticipation of new variants being produced. If it had not been for World War I, the Ilya Muromets would probably have started passenger flights that same year. With the beginning of World War I, Sikorsky was encouraged by the results of the proving flights to redesign the aircraft to become the "Military Ilia Mourometz, Type V, the world's first purpose-designed heavier than air bomber. The new heavy bomber was slightly smaller and lighter than the Type A. Internal racks carried up to 800 kg of bombs, and positions for
