Ilya Muromets (Илья Муромец), named after the Russian folk hero, is a very steep vertical waterfall on the Bear's Peninsula of Iturup, one of the Kuril Islands.
 The water stream falls abruptly from the eastern slope of the Demon Volcano into the Pacific Ocean.
 With a height of 141 meters, it is one of the highest waterfalls in the Russian Far East.
 Ilya Muromets is rarely seen by tourists, however, because it can be accessed only by boat.
The Sikorsky "Ilya Muromets" (Russian: Сикорский Илья Муромец ) (Sikorsky S-22, S-23, S-24, S-25, S-26 and S-27) were a class of Russian pre-World War I large four-engine commercial airliners and military heavy bombers used during World War I by the Russian Empire.
 The aircraft series was named after Ilya Muromets, a hero from Slavic mythology.
 The series was based on the Russky Vityaz or Le Grand, the world's first four-engined aircraft, designed by Igor Sikorsky.
 The Ilya Muromets aircraft as it appeared in 1913 was a revolutionary design, intended for commercial service with its spacious fuselage incorporating a passenger saloon and washroom on board.
 During World War I, it became the first four-engine bomber to equip a dedicated strategic bombing unit.
 This heavy bomber was unrivaled in the early stages of the war, as the Central Powers had no aircraft capable enough to rival it until much later.
 The Zeppelin-Staaken R.VI of 1916-17 was the only example of any of the Imperial German "Riesenflugzeug" airframe designs to be produced in any quantity during World War I.
