Context: Willem Johannes Witteveen (] ; 5 May 195217 July 2014) was a Dutch legal scholar, politician, and author.  He was a law professor at Tilburg University (1990–2014) and a Member of the Senate for the Labour Party (1999–2007; 2013–2014).  He was also the author of several books about law and politics.  Witteveen was killed on 17 July 2014 when the flight he was travelling on, Malaysia Airlines Flight 17, was shot down over eastern Ukraine. Uruguayan Air Force Flight 571 was a chartered flight carrying 45 people, including a rugby union team, their friends, family, and associates, that crashed in the remote Andes in early spring (Southern Hemisphere) on 13 October 1972, in extremely heavy snowpack -34.765 degrees latitude south of the equator, in an incident known as the Andes flight disaster and, in the Hispanic world and South America, as the Miracle of the Andes ("El Milagro de los Andes").  More than a quarter of the passengers died in the crash, and several others quickly succumbed to cold and injury.  Of the 27 who were alive a few days after the accident, another eight were killed by an avalanche that swept over their shelter in the wreckage.  The last 16 survivors were rescued on 23 December 1972, more than two months (72 days) after the crash. Seaboard World Airlines Flight 253A was a military charter flight carrying 214 American troops bound for South Vietnam.  On July 1, 1968, the plane was intercepted by Soviet jets after it unintentionally violated Soviet airspace.  It was forced to land on one of the Soviet-controlled Kuril Islands with all 238 Americans aboard being detained for two days. Thomas Joseph O'Malley (October 15, 1915 – November 6, 2009), better known as T. J. O'Malley, was an Irish-American aerospace engineer who, as chief test conductor for the Convair division of General Dynamics, was responsible for pushing the button on February 20, 1962 launching the Mercury-Atlas 6 space flight carrying astronaut John Glenn, the first American in orbit.  Five years later, NASA asked North American Aviation to hire him as director of launch operations to help get the Apollo program back on track after the Apollo 1 command module fire on the launch pad killed three astronauts.  O'Malley continued to play a leadership role in the United States' space program through the first space shuttle launch in 1981. Arrow Air Flight 1285 was a McDonnell Douglas DC-8 jetliner that operated as an international charter flight carrying U.S. troops from Cairo, Egypt, to their home base in Fort Campbell, Kentucky, via Cologne, West Germany and Gander, Canada. A crush load is a level of passenger loading in a transport vehicle which is so high that passengers are "crushed" against one another.  It represents an extreme form of passenger loading, and normally considered to be representative of a system with serious capacity limitations.  Crush loads result from too many passengers within a vehicle designed for a much smaller number.  Crush loaded trains or buses are so heavily loaded that for most passengers physical contact with several other nearby passengers is impossible to avoid. Harbor Gateway Transit Center (formerly Artesia Transit Center) is a Metro Silver Line station and a large bus station at southern end of the Harbor Transitway located in the southwest corner of Interstate 110 (Harbor Freeway) and State Route 91 (Gardena Freeway) in Harbor Gateway close to Carson.  The station has 12 bus bays and 900 park and ride spaces, and is the southern terminus of the Metro Silver Line (line 910 only).  Many passengers connect to this station from other buses to transfer to the Silver Line.  Public restrooms for passengers as began installation in October 2012 and opened in February 2013.  The nextrip bus screens were installed in November 2012 and became fully functional in April 2013.  The large hub is undergoing station improvements. Malaysia Airlines Flight 17 (MH17/MAS17) was a scheduled passenger flight from Amsterdam to Kuala Lumpur that was shot down on 17 July 2014 while flying over eastern Ukraine, killing all 283 passengers and 15 crew on board.  Contact with the aircraft, a Boeing 777-200ER, was lost about 50 km from the Ukraine–Russia border and wreckage of the aircraft landed near Torez in Donetsk Oblast, Ukraine, 40 km from the border.  The crash occurred in an area controlled by the Donbass People's Militia during the Battle in Shakhtarsk Raion, part of the ongoing war in Donbass.  The crash is the deadliest airliner shootdown, eighth-deadliest aviation disaster, and was Malaysia Airlines' second aircraft loss during 2014 after the disappearance of Flight 370 on March 8. Asiana Airlines Flight 733 (Flight OZ733, registration HL7229) was a domestic Asiana Airlines passenger flight between Seoul Gimpo International Airport (SEL at the time) and Mokpo Airport (MPK), South Korea.  The flight carrying 110 passengers along with six crew members departed Seoul at 14:37 for a short flight to Mokpo Airport.  On approach to runway 06, the aircraft crashed into a ridge, Mt. Ungeo, at 800 feet (240 m) on July 26, 1993, at 15:48.  The aircraft, a Boeing 737-5L9, failed to land twice in bad weather (heavy rain and wind) and crashed on the third attempt, causing the deaths of 66 passengers and two crew members.  Mokpo Airport was only equipped with VOR/DME. A bus (archaically also omnibus, multibus, motorbus, autobus) is a road vehicle designed to carry many passengers. Buses can have a capacity as high as 300 passengers.  The most common type of bus is the single-decker rigid bus, with larger loads carried by double-decker and articulated buses, and smaller loads carried by midibuses and minibuses; coaches are used for longer-distance services.  Many types of buses, such as city transit buses and inter-city coaches, charge a fare.  Other types, such as elementary or secondary school buses or shuttle buses within a post-secondary education campus do not charge a fare.  In many jurisdictions, bus drivers require a special licence above and beyond a regular driver's licence.
