History
Bubble canopies have been in use since before World War II, with some experimental bubble canopy designs in the World War I era. The British had already developed the "Malcolm hood", which was a bulged canopy, but the British Miles M.20 was one of the first aircraft designs to feature a true bubble canopy. Although it never went into production the concept of the bubble canopy was utilised on other British aircraft, such as the Hawker Typhoon and Tempest. It was also fitted to the P-51 Mustang and P-47 Thunderbolt amongst others.

Famous quotes containing the word history:
“A poet’s object is not to tell what actually happened but what could or would happen either probably or inevitably.... For this reason poetry is something more scientific and serious than history, because poetry tends to give general truths while history gives particular facts.”
—Aristotle (384–323 B.C.)
“Every member of the family of the future will be a producer of some kind and in some degree. The only one who will have the right of exemption will be the mother ...”
—Ruth C. D. Havens, U.S. suffragist. As quoted in History of Woman Suffrage, vol. 4, ch. 13, by Susan B. Anthony and Ida Husted Harper (1902)
“History does nothing; it does not possess immense riches, it does not fight battles. It is men, real, living, who do all this.... It is not “history” which uses men as a means of achieving—as if it were an individual person—its own ends. History is nothing but the activity of men in pursuit of their ends.”
—Karl Marx (1818–1883)
