STS-5
"Columbia" landed on Runway 22 at Edwards Air Force Base on 16 November 1982, at 6:33 am PST, having traveled 2 million miles in 81 orbits during a mission that lasted 5 days, 2 hours, 14 minutes and 26 seconds. "Columbia" was returned to KSC on 22 November 1982. STS-5 was the first shuttle flight in which the crew did not wear pressure suits for the launch, reentry, and landing portions of the flight, similar to the Soviet Voskhod and Soyuz missions prior to the ill-fated Soyuz 11 mission in 1971.
The shuttle was formally declared "operational" after STS-4. However, the Columbia Accident Investigation Board (CAIB), in its report on the loss with all crew aboard of "Columbia" during STS-107 in 2003, asserted that the orbiter should never have been considered operational and that, while not intrinsically unsafe, it was in fact an experimental vehicle. The CAIB's rationale was that civilian and military aircraft that are considered operational must have been tested and proven over thousands of safe flights in their final operational configurations, whereas the shuttle had conducted under 200 flights, with continuous modification. NASA operated the Space Shuttle as an experimental vehicle for the remainder of the program.
Reconstruction era
On April 20, 1871, the U.S. Congress launched a 21-member investigation committee on the status of the Southern Reconstruction states: North Carolina, South Carolina, Georgia, Mississippi, Alabama, and Florida. Congressional members on the committee included Rep. Benjamin Butler, Sen. Zachariah Chandler, and Sen. Francis P. Blair. Subcommittee members traveled into the South to interview the people living in their respective states. Those interviewed included top-ranking officials, such as Wade Hampton, former South Carolina Gov. James L. Orr, and Nathan B. Forrest, a former Confederate general and (alleged) prominent Ku Klux Klan leader (Forrest denied in his Congressional testimony being a member). Other southerners interviewed included farmers, doctors, merchants, teachers, and clergymen. The committee heard numerous reports of white violence against blacks, while many whites denied Klan membership or knowledge of violent activities. The majority report by Republicans concluded that the government would not tolerate any Southern "conspiracy" to resist violently the Congressional Reconstruction. The committee completed its 13-volume report in February 1872. While Grant had been able to suppress the KKK through the Enforcement Acts, other paramilitary insurgents organized, including the White League in 1874, active in Louisiana; and the Red Shirts, with chapters active in Mississippi and the Carolinas. They used intimidation and outright attacks to run Republicans out of office and repress voting by blacks, leading to white Democrats regaining power by the elections of the mid-to-late 1870s.
