input: Mountain Jews are considered, by some, to be of Sephardic lineage; this however is a misnomer as they are neither Sephardim (from the Iberian Peninsula) nor Ashkenazim (from Germany and Eastern-Europe) but rather come directly by way of Persia. Mountain Jews tenaciously held to their religion throughout the centuries, developing their own unique traditions and religious practices. Mountain Jewish traditions are infused with teachings of Kabbalah and Jewish mysticism. Mountain Jews have traditionally maintained a two-tiered rabbinate, distinguishing between a rabbi and a "dayan." A "rabbi" was a title given to religious leaders performing the functions of liturgical preachers (maggids) and cantors (hazzans) in synagogues ("nimaz"), teachers in Jewish schools (cheders), and shochets. A Dayan was a chief rabbi of a town, presiding over beit dins and representing the highest religious authority for the town and nearby smaller settlements. Dayans were elected democratically by community leaders. The religious survival of the community was not without difficulties. In the prosperous days of Jewish Valley (roughly 1600-1800), the spiritual center of Mountain Jews centered on the settlement of Aba-Sava. Many works of religious significance were written in Aba-Sava. Here, Elisha ben Schmuel Ha-Katan wrote several of his piyyuts. Theologist Gerhson Lala ben Moshke Nakdi, who lived in Aba-Sava in 18th century, wrote a commentary to Mishneh Torah of Maimonides. Rabbi Mattathia ben Shmuel ha-Kohen wrote his kabbalistic essay Kol Hamevaser in Aba-Sava. With the brutal destruction of Aba-Sava (roughly 1800), however, the religious center of Mountain Jews moved to Derbent. Prominent rabbis of Mountain Jews in the nineteenth century included: Rabbi Gershom son of rabbi Reuven of Qirmizi Q@s@b@ Azerbaijan, Shalom ben Melek of Temir-Khan-Shura (modern Buynaksk), Chief Rabbi of Dagestan Jacob ben Isaac, and Rabbi Hizkiyahu ben Avraam of Nalchik, whose son Rabbi Nahamiil ben Hizkiyahu later played a crucial role in saving Nalchik's Jewish community from the Nazis. In the early decades of the Soviet Union, the government took steps to suppress religion. Thus, In the 1930s, the Soviet Union closed synagogues belonging to mountain Jews. Same procedures were implemented on other ethnicities and religions. Soviet authorities propagated the myth that Mountain Jews were not part of the world Jewish people at all, but rather members of Tat community that settled in the region. Soviet anti-Zionism rhetoric was intensified during Khrushchev's rule. Some of the synagogues were later reopened in the 40's. The closing of the synagogues in the 30's was part of communist ideology, which resisted religion of any kind. At the beginning of the 1950s, there were synagogues in all major Mountain Jewish communities. By 1966, reportedly six synagogues remained; some were confiscated by the Soviet authorities. While Mountain Jews observed the rituals of circumcision, marriage and burial, as well as Jewish holidays, other precepts of Jewish faith were observed less carefully. The community's ethnic identity remained unshaken despite the Soviet efforts. Cases of intermarriage with Muslims in Azerbaijan or Dagestan were rare as both groups practice endogamy. After the fall of the Soviet Union, Mountain Jews experienced a significant religious revival, with increasing religious observance by members of the younger generation.

input: The War Production Board (not the military) originally contracted with Henry Kaiser and Hughes to produce the gigantic HK-1 Hercules flying boat for use during World War II to transport troops and equipment across the Atlantic as an alternative to seagoing troop transport ships that were vulnerable to German U-boats. The project was opposed by the military services, thinking it would siphon resources from higher priority programs, but was advocated by Hughes' powerful allies in Washington, D.C. After disputes, Kaiser withdrew from the project and Hughes elected to continue it as the H-4 Hercules. However, the aircraft was not completed until after the end of World War II. The Hercules was the world's largest flying boat, the largest aircraft made from wood, and, at 319 feet 11 inches (97.51 m), had the longest wingspan of any aircraft (the next largest wingspan was about 310 ft (94 m)). (The Hercules is no longer the longest or heaviest aircraft ever built; both of those titles are currently held by the Antonov An-225 Mriya.) The Hercules flew only once for one mile (1.6 km), and 70 feet (21 m) above the water, with Hughes at the controls, on November 2, 1947. The Hercules was nicknamed the Spruce Goose by its critics, but it was actually made largely from birch, not spruce, rather than of aluminum, because the contract required that Hughes build the aircraft of "non-strategic materials". It was built in Hughes' Westchester, California, facility. In 1947, Howard Hughes was summoned to testify before the Senate War Investigating Committee to explain why the H-4 development had been so troubled, and why $22 million had produced only two prototypes of the F-11. General Elliott Roosevelt and numerous other USAAF officers were also called to testify in hearings that transfixed the nation during August and November 1947. In hotly disputed testimony over TWA's route awards and malfeasance in the defense acquisition process, Hughes turned the tables on his main interlocutor, Maine Senator Owen Brewster, and the hearings were widely interpreted as a Hughes victory. After being displayed at the harbor of Long Beach, California, the Hercules was moved to McMinnville, Oregon, where it is now part of the Evergreen Aviation & Space Museum. On November 4, 2017, the 70th anniversary of the only flight of the H-4 Hercules was celebrated at the Evergreen Aviation & Space Museum with Hughes' paternal cousin Michael Wesley Summerlin and Brian Palmer Evans, son of Hughes radio technology pioneer Dave Evans, taking their positions in the recreation of a photo that was previously taken of Hughes, Dave Evans and Joe Petrali on board the H-4 Hercules.
