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:
“We aspire to be something more than stupid and timid chattels, pretending to read history and our Bibles, but desecrating every house and every day we breathe in.”
