IN: The Hereditary peers form part of the peerage in the United Kingdom. As of 1999, there were about 800 peers holding titles that could be inherited. Not all hereditary titles are titles of the peerage. For instance, baronets and baronetesses may pass on their titles, but they are not peers.

Until 1963 peers could not disclaim their peerage in order to sit in the House of Commons, and thus a peerage was sometimes seen as an impediment to a future political career. In 1999, the House of Lords Act abolished the automatic right of hereditary peers to sit in the House of Lords. Out of about 750 hereditary peers, only 92 may sit in the House of Lords. The Act provides that 90 of those 92 seats are to be elected by other members of the House: 15 by vote of the whole house (including life peers), 42 by the Conservative hereditary peers, two by the Labour hereditary peers, three by the Liberal Democrat hereditary peers, and 28 by the crossbench hereditary peers. Elections were held in October and November 1999 to choose those initial 90 peers, with all hereditary peers eligible to vote. Hereditary peers elected hold their seats until their death, resignation or exclusion for non-attendance (the latter two means introduced by the House of Lords Reform Act 2014), at which point by-elections are held to maintain the number at 92. The remaining two hold their seats by right of the hereditary offices of Earl Marshal and Lord Great Chamberlain. These offices are hereditary in themselves, and in recent times have been held by the Dukes of Norfolk and the Marquesses of Cholmondeley respectively. These are the only two hereditary peers whose right to sit is automatic. The Government reserves a number of political and ceremonial positions for hereditary peers. To encourage hereditary peers in the House of Lords to follow the party line, a number of Lords-in-Waiting (government whips) are usually hereditary peers. This practice was not adhered to by the Labour government of 1997-2010 due to the small number of Labour hereditary peers in the House of Lords.

Is there any additional information about the peer roles in the House of Lords?

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.
