Context paragraphs:
Iraqi nationality law: The first nationality law was passed in 1924, and on the 6 August that year, all people within the bounds of Iraqi jurisdiction automatically acquired Iraqi citizenship.

Timeline of space travel by nationality: Since the first human spaceflight by the Soviet Union, citizens of 40 countries have flown in space.  For each nationality, the launch date of the first mission is listed.  The list is based on the nationality of the person at the time of the launch.  Only 3 of the 40 "first flyers" have been women (Helen Sharman for the United Kingdom in 1991, Anousheh Ansari for Iran in 2006, and Yi So-yeon for South Korea in 2008).  Only three nations (Soviet Union/Russia, U.S., China) have launched their own manned spacecraft, with the Soviets/Russians and the American programs providing rides to other nations' astronauts.  Twenty-six "first flights" occurred on Soviet or Russian flights while the United States carried thirteen.

Czechoslovak Legion (1939): Czechoslovak Legion of 1939 was formed in Second Polish Republic after Germany occupied Czechoslovakia in March 1939.  While about 4,000 Czechs and Slovaks joined the French Foreign Legion, about a 1,000 chose to go to Poland, which looked likely to be involved in hostilities with Germany in the near future, and which gave permission for a formation of a dedicated Czechoslovak unit, in tradition of the First World War Czechoslovak Legions.  The Legion had a strength of about 700 soldiers, under the command of Lieutenant-Colonel Ludvík Svoboda; about 200 flying personnel were instead assigned to a "Czechoslovak Reconnaissance Squadron".  The ground Legion was however not fully formed by the time of German invasion of Poland on 1 September.  Most of the soldiers were eventually interned by the invading Soviets on 17 September, while others crossed the Polish-Romanian border and were interned in Romania.  The Reconnaissance Squadron was involved in the fight in the air alongside the Polish Air Force, although primarily in the reconnaissance role, as the aircraft they received from Poland (Potez XXV, RWD-8 and PWS-26), were mostly obsolete in air combat.

Superbus (transport): The Superbus is a prototype high speed electric coach-like limo car that is capable of carrying 23 passengers at speeds of up to 250 km/h on specially designed segregated highway lanes.  The Superbus project, led by Dutch astronaut professor Wubbo Ockels of the Delft University of Technology until his death in 2014 envisages a comfortable, demand-dependent door-to-door transportation rivaling the car and the train.  The project, which encompass infrastructure, logistics, safety, reliability and economic viability, in addition to the design of the vehicle itself, has received funding of €7 million, largely provided by the Dutch State.

Ivan Bella: Ivan Bella (born 25 May 1964 in Brezno, Czechoslovakia (now Slovakia)) is a Slovak Air Force officer who became the first Slovak citizen to fly in space.  He participated in an eight-day joint Russian-French-Slovak mission to the Mir space station in 1999.

Ampyx Power: Ampyx Power is an airborne wind energy company founded in 2008 by Bas Lansdorp and Richard Ruiterkamp.  It was created after Lansdorp dropped his five-year-long studies of wind energy at Delft University of Technology to found Ampyx Power.  In 2011, Lansdorp sold a majority of his Ampyx Power shares to fund his new project, Mars One.  Wubbo Ockels' interest in energy began when he let a kite line slip and it burned his hand.  He became interested and started to study and research how this could be turned into electricity.  At Delft University, he formed a team with Bas Lansdorp that worked on developing kites that could retrieve energy from the sky.  Richard Ruiterkamp became the team leader and he created a fixed wing aircraft that allowed greater controllability and allowing the generation of more energy.  In 2008 he founded the company with Bas Lansdorp.  Lansdorp worked on the business aspect, and Ruiterkamp was head of the science division.  Currently, Ampyx Power has a team of 40 engineers.  Their current prototype is the AP3 Ampyx Power Airborne Wind Energy System (AWES).  The system is a tethered aircraft that converts wind into electric energy.  The aircraft is tethered to an on the ground generator.  When the aircraft moves and flies, it reels the tether and powers the generator.  The plane is then reeled in through the tether and then re-released into the air.

NASA Astronaut Group 9: NASA Astronaut Group 9 was announced on May 29, 1980, and completed their training by 1981.  This group, composed of 19 candidates, was selected to supplement the 35 astronauts that had been selected in 1978, and marked the first time that non-Americans were trained as mission specialists with the selections of ESA astronauts Claude Nicollier and Wubbo Ockels.  In keeping with the previous group, astronaut candidates were divided into pilots and mission specialists, with eight pilots, eleven mission specialists, and two international mission specialists within the group.

Wubbo Ockels: Wubbo Johannes Ockels (28 March 1946 – 18 May 2014) was a Dutch physicist and an astronaut of the European Space Agency (ESA).  In 1985 he participated in a flight on the space shuttle Challenger, STS-61-A, making him the first Dutch citizen in space.  After his astronaut career, Ockels was professor of "Aerospace for Sustainable Engineering and Technology" at the Delft University of Technology.

Soyuz TM-29: Soyuz TM-29 was a Russian manned spacecraft launched from the Baikonur Cosmodrome aboard a Soyuz 11A511U rocket.  It docked with Mir on February 22 at 05:36 GMT with Cosmonauts Viktor Afanasyev of Russia, Jean-Pierre Haigneré of France, and Ivan Bella of Slovakia aboard.  Since two crew seats had been sold (to Slovakia and France), Afanasyev was the only Russian cosmonaut aboard.  This meant that Russian engineer Avdeyev already aboard Mir would have to accept a double-length assignment.  After the February 27 departure of EO-26 crew commander Padalka and cosmonaut Bella aboard Soyuz TM-28, the new EO-27 Mir crew consisted of Afanasyev as Commander, Avdeyev as Engineer and French cosmonaut Haigneré.

Thai nationality law: Thai nationality law includes principles of both "jus sanguinis" and "jus soli".  Thailand's first Nationality Act was passed in 1913.  The most recent law dates to 2008.
