Zero 2000, Kodak Ektar, 4 minutes
The leaving is, perhaps, the worst part. That point in a trip when you have to leave, but you have to work hard at getting back home. It took me two full days to get to Suriname, and two full days to get back. It is a testament to the goodness of the country that I arrived home after 48 hours, four flights, and one dingy hotel still feeling relaxed and happy. I had a wonderful time, and would love to return. Next time, though, I will speak a little Dutch.

The Mitsubishi A6M Zero was a lightweight fighter aircraft operated by the Imperial Japanese Navy Air Service (IJNAS) from 1940 to 1945. It was by far the most famous and widely used aircraft in Japanese aviation history. The origin of its official designation was “A” signifying a fighter and “6” signifying the sixth model built by Mitsubishi “M.”
It is universally known as the “Zero” from its Japanese Navy designation, Type “0” Carrier Fighter, taken from the last digit of the Imperial year 2600 (1940) when it entered service. In Japan, it was unofficially referred to as both “Rei-sen” and “Zero-sen;” Japanese pilots most commonly called their planes “Zero-sen.” The official Allied code name was “Zeke” in keeping with the practice of giving boys’ names to Japanese fighters, girls’ names to bombers, bird names to gliders, and tree names to trainers.
It was a modern monoplane for the time, capable of speeds over 300 mph, yet its low landing speed also made it suitable for carrier operations. Everything about its design and construction emphasized lightness, simplicity, and utility. The first Zero was flown in April 1939 and went into regular service with the Japanese Navy in July 1940. A total of 10,450 examples were produced from 1939 to 1945, more than any other type of Japanese military aircraft. The Zero played an important role in almost every Japanese naval action, from Pearl Harbor all the way through to the Japanese surrender in August 1945. Even though it was considered obsolete after 1943, the aircraft continued in production until the last days of the war.
Since most of Japan’s carrier fleet had been sunk by 1944, the Japanese Navy ordered new Zeros designed with more reliable bomb racks to fulfill the mission of dive bombing and to operate from smaller carriers. The Model 63 with a special bomb rack, reinforced tailplane, and 350-liter wing drop tanks was put into production in May 1945. However, with no aircraft carriers available at this time, most surviving Zeros were converted into Kamikaze or suicide attack planes. In the last months of the war, the A6M7 was the final line of defense of the home islands, assuming the additional role of night fighter.
This Zero, built in 1945, was transported from the Yokohama Naval Air Station in Japan at the end of hostilities aboard the carrier USS Wasp (CV-18), and stored at the U.S. Naval Air Station at Willow Grove, PA. In 1962, it was acquired by the National Air and Space Museum, and then in turn, sent to the Bradley Air Museum in Connecticut for restoration, but storm damage to the museum prevented this from happening. The aircraft was then loaned to the San Diego Air and Space Museum, where it arrived dismantled and in boxes in March of 1981. Museum volunteers spent over 12,000 hours restoring the plane, which has been on display in the WWII gallery since April of 1984. It is currently on permanent loan from the National Air and Space Museum. Prior to my visit, I had little to no idea that this model of the Zero even existed!

In phone dials and in normal computer keyboards zero appears after nine and not before one, were it should have been. Interestingly, nine is far from the zero in the 10 exactly like the one from the zero before it.
In computer keyboard designed just for numbers zero appears before one.
First keyboards did not have zero at all since they used in place the letter O.
Ordinal numbers start from one and not from zero: No one counts: none, first, second ...

Origen del Nombre
En la epoca en que se estaba desarrollando el tercer prototipo del caza japones, a los modelos producidos para la aviacion naval se les asignaba los números de tipo basados en el último número del año japones corriente, y como 1940 era el año 2600 en el calendario japonés, la serie A6M fue conocida como Zero .
La Invencibilidad Japonesa
Para los Japoneses el Zero era todo lo que el Spitfire representó para la nación Britanica. Simbolizaba la conducta de la guerra de Japon. El caza Zero marcó el inicio de una nueva época en la aviación naval de guerra. Fue el primer caza basado en un portaaviones capaz de vencer a sus oponentes basados en tierra. Creó un mito, el mito de la invencibilidad japonesa en el aire. Mito bajo el cual los propios Japoneses caerían víctimas como resultado de la casi total destrucción del poder aereo aliado en los primordios de la guerra del Pacifico. En su época el Zero era el mejor caza de combate basado en portaaviones, y su aparición sobre Pearl Harbor vino como una completa sorpresa para las fuerzas americanas.
Diseño
El zero fue originalmente concebido como reemplazo del caza Mitsubishi tipo 96 (A5M), el primer monoplano de la marina japonesa. En Octubre 5 de 1937, la marina japonesa entregó sus requerimientos a las compañías Mitsubishi y Nakajima para un nuevo caza con una velocidad máxima de 310 m.p.h, la habilidad de subir a 9,840 pies en 3.5 minutos, maniorabilidad y autonomía excediendo cualquier caza existente y un armamento de dos cañones y dos ametralladoras. Estas demandas estabas por lejos en exceso de cualquier pedido solicitado a la industria aerea japonesa, y considerando estos pedidos poco realistas, la compañía Nakajima se retiró del proyecto luego después de una reunión de diseñollevada a cabo en la ciudad de Yokosuka el 17 de Enero de 1938. La Mitsubishi sola aceptó la tarea de cumplir con los requerimientos del "12-Shi" (doceavo año del reinado Showa) como era conocido el proyecto, y el trabajo de diseño inició bajo la dirección de Jiro Horikoshi, jefe de diseño de la Mitsubishi Jukogyo K.K.
El motor escogido fue el Mitsubishi MK2 Zuisei 13, un motor radial de 14 cilindros con 780 HP, mas tarde conocido dentro del sistema unificado de designacón JNAF/JAAF como el Ha.31/13. Este motor fue escogido debido a su poco peso y pequeño diámetro, y se le colocó una hélice de velocidad constante de dos aspas. Extremo cuidado se le dió al peso estructural debido a que la maniobrabilidad estaba diractamente relacionada al peso de las alas, y se hizo extensivo uso del Duraluminio Extra Super, una resistente y leve aleación desarrolada para aviones por la Sumitoma Metal Industry Company. El trabajo con el prototipo progresó rápidamente, y los cambios solicitados despues de las inspecciones del diseño 12-shi el 17 de Abril y 11 de Julio de 1938 fueron progresivamente incorporados.
Prueba del Primer Prototipo
El 16 de Marzo de 1939, en la planta Mitsubishi de Nagoya, el primer prototipo fue terminado. Pruebas del motor fueron conducidas en Marzo 18, y la aeronave fue transferida a la base aeronaval de Kasumigaura para la prueba de vuelo. Aquí, el 1ro de Abril de 1939, uno de los pilotos de prueba de la Mitsubishi, Katsuzo shima, voló el nuevo caza por la primera vez. El vuelo fue un inmediato suceso, siendo el único problema que se presentó el de los frenos de las ruedas, el sistema de aceite, y una tendencia pequeña a vibrar. Las pruebas siguientes indicaron que la vibración podía ser controlada mediante el uso de una hélice de mayor tamaño del tipo de tres aspas. El prototipo fue aceptado por la marina el 14 de Septiembre de 1939, como el Caza de Portaaviones A6M1, y mientrastanto, un segundo prototipo se había terminado, pasando las pruebas de vuelo del fabricante el 18 de Octubre de 1939, aceptándose por la marina una semana despues. Ambos prototipos A6M1 cargaban dos cañones de 20mm en las alas y dos ametralladoras de 7.7mm en la parte superior del fuselaje.
Mientras las pruebas del A6M1 continuaban, un nuevo motor pasó las pruebas de la marina, el Nakajima NK1C Sakae 12 de 925 HP, que era ligeramente mayor y mas pesado que el Zuisei. La marina decidió instalar este motor en el tercer prototipo que sería conocido como A6M2.
