Blood chit
A blood chit () is a notice carried by military personnel and addressed to any civilians who may come across an armed-services member – such as a shot-down pilot – in difficulties. As well as identifying the force to which the bearer belongs as friendly, the notice displays a message requesting that the service member be rendered every assistance. Etymology. Alternative names are escape and identification flags (). Chit (also 'chitty') is a British English term for a small document, note or pass, representing a debt to be paid; it is an Anglo-Indian word dating from the late 18th  century, derived from the Hindi "citthi". History. The first blood chit may have been made in 1793 when French balloonist Jean-Pierre Blanchard demonstrated his hot air balloon in the United States. Because he could not control the direction of the balloon, no one knew where he would land. Because Blanchard did not speak English, George Washington, according to legend, gave him a letter that said that all U.S. citizens were obliged to assist him to return to Philadelphia. In World War I, British Royal Flying Corps pilots in India and Mesopotamia carried a "goolie chit" printed in four local  languages that promised a reward to anyone who would bring an unharmed British aviator back to British lines. The British officer John Masters recorded in his autobiography that Pathan women in the North-West Frontier Province (1901–1955) of British India (now modern day Pakistan) during the Anglo-Afghan Wars would behead and castrate non Muslim soldiers who were captured, like British and Sikhs. In the Second Sino-Japanese War prior to World War II, foreign volunteer pilots of Flying Tigers carried notices printed in Chinese that informed the locals that this foreign pilot was fighting for China and they were  obliged to help them. A text from one such blood chit translates as follows: I am an American airman. My plane is destroyed. I cannot speak your language. I am an enemy of the Japanese. Please give me food and take me to the nearest Allied military post. You will be rewarded. On the UN chit from the Korean war, it is written in Japanese that cooperators will be rewarded and should help for his own 'benefit'. United States Armed Forces. When the U.S. officially entered World War II in December 1941, flight crew survival kits included blood chits  printed in 50 different languages that sported an American flag and promised a reward for a safe return of a pilot.

Some units added the blood chit to the crew's flight suits while other units gave the blood chit out only for specific flights. Currently, blood chits are a product of the Joint Personnel Recovery Agency.
