A book presently available on this topic is Airmen Without Portfolio by J.C. Edwards , devoted to the memory of FG Tinker . It refers to entire paragraphs from Some Still Live , including pictures of Tinker and his handwritten flight logbook .

Hemingway 's influence on the style is rather evident : the language is simple but full of human emotion while the war scenes are live and the text creates colorful pictures to the reader . - The Spanish Republican Air Force was the air arm of the Armed Forces of the Second Spanish Republic, the legally established government of Spain between 1931 and 1939. - The Second Spanish Republic (in Spanish: "Segunda Republica Espanola") was the republican regime that existed in Spain from 1931 to 1939, preceded by the Restoration and followed by Francoist Spain after the Spanish Civil War.

It occurs naturally in citrus fruits. In biochemistry, it is an intermediate in the citric acid cycle, which occurs in the metabolism of all aerobic organisms. - The Monkees are an American-British pop rock band originally active between 1965 and 1971, with subsequent reunion albums and tours in the decades that followed.

It is created by the reaction of lactic acid with calcium carbonate or calcium hydroxide. - Jo Hyun - jae ( born May 9 , 1980 ) is a South Korean actor . Jo made his entertainment debut as a singer in the four - member K - pop boy band Guardian , which disbanded after releasing their self - titled album in 1998 .

The first boy bands consisted of the Beatles, Jackson 5, the Monkees, and the Osmonds singing love songs marketed towards young females. Being vocal groups, most boy band members do not play musical instruments, either in recording sessions or on stage, making the term something of a misnomer. However, exceptions do exist. Many boy bands dance as well as sing, usually giving highly choreographed performances. - A misnomer is a word or term that suggests a meaning that is known to be wrong. Misnomers often arise because the thing received its name long before its true nature was known, or because the nature of an earlier form is no longer the norm. A misnomer may also be simply a word that is used incorrectly or misleadingly. "Misnomer" does not mean "misunderstanding" or "popular misconception", and many misnomers remain in legitimate use (that is, being a misnomer does not always make a name incorrect). - Sodium chloride , also known as salt or halite, is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions.

In the form of edible or table salt it is commonly used as a condiment and food preservative. Large quantities of sodium chloride are used in many industrial processes, and it is a major source of sodium and chlorine compounds used as feedstocks for further chemical syntheses. A second major application of sodium chloride is de-icing of roadways in sub-freezing weather. - Pocari Sweat is a mild-tasting, relatively light, non-carbonated sweet beverage and is advertised as an "ion supply drink".
