Why pilots say Mayday and 9 other codewords everyone should know

In situations where clear communication is paramount, especially when lives are at stake, professionals often rely on standardized codewords and phonetic alphabets designed to prevent confusion. Either from movies or from personal experience, it's probable that you've heard at least some of these before, and many have found their way into everyday conversation. Let's find out how many of these code expressions you can recognize.

Mayday is the international distress call used when the sender is in immediate, life-threatening danger. Pilots and mariners use it to signal that they require urgent assistance due to situations such as engine failure, fire, flooding, or medical emergencies.

The word was introduced in 1923 by British radio officer Frederick Stanley Mockford, who based it on the French phrase m'aider, meaning "help me," in an attempt to make it internationally recognizable. Hearing this transmission immediately alerts emergency responders that every second counts.

Not every emergency is severe enough to warrant a mayday call. When a crew faces a problem that is urgent but not immediately life-threatening, the appropriate codeword is Pan-Pan.

Like mayday, it comes from French: it derives from panne, meaning a breakdown or mechanical failure. A Pan-Pan call might be used if an aircraft loses an engine but can still fly safely, or if a ship experiences equipment problems while remaining under control. It tells responders that assistance is needed, but that the situation has not yet become critical.

Few emergency signals are as universally recognizable as SOS. Contrary to popular belief, the letters do not officially stand for "Save Our Ship" or "Save Our Souls." It was adopted in 1906 because SOS is an extremely simple, easy-to-transmit, and unmistakable pattern in Morse code.

SOS remains one of the world's most enduring distress signals, and it's still recognized by rescue organizations all around the globe.

In the NATO phonetic alphabet, each letter is assigned a unique word to eliminate confusion when radio transmissions are distorted by noise or poor reception. If you've ever heard someone spell a name as "Mike Alpha Romeo Yankee," you've encountered the NATO phonetic alphabet.

The system was officially adopted by NATO in the 1950s and is now widely used by militaries, airlines, emergency responders, and many police departments worldwide. Using it greatly reduces the chance of misunderstanding important information over radio.

Roger dates back to the early days of radio communication, when the letter R stood for "received." Before the adoption of the NATO alphabet, the US military used Roger instead of Romeo to represent that letter_._

Although modern communications systems have changed and the US military has fully embraced the use of the NATO alphabet, Roger remains standard aviation terminology, and it's one of the best-known radio acknowledgments in the world. It conveys a very simple but important meaning: "I have received and understood your message."

Although many people assume Roger and Wilco mean the same thing, they actually convey different messages. Wilco is short for "will comply." In other words, it tells the sender not only that the message was received and understood, but that the instruction will be carried out.

Saying both Roger and Wilco is technically redundant in proper radio communication, since complying necessarily implies understanding, but the combination is often heard in movies and television.

In the NATO phonetic alphabet, Tango simply represents the letter T. However, US military personnel have also adopted it as a shorthand when referring to a target or a hostile.

This secondary meaning became widely known through military operations in the twentieth century and has since appeared in countless books, films, and video games in phrases like "We've got one Tango moving north."

Oscar Mike, NATO for the letters O and M, is military shorthand for "On the Move." It's a quick way of reporting that a unit has begun moving toward its objective.

The expression is especially common in the US military and has become more familiar to the general public through documentaries, memoirs, and films. It's finding its way into civilian life, meaning simply "I'm heading out."

Ten-codes were developed during the 1930s to allow for brevity and standardization of message traffic in radio communications. They were widely adopted by US public safety departments and by radio enthusiasts.

While the system is being slowly phased out in favor of plain language communications, many local police, fire, and sheriff departments keep using it, and it is still strongly associated with radio culture by the general public. One of the most famous ten-codes is 10-4, meaning "received and understood."

Hospitals around the world use color-coded announcements to communicate emergencies without causing unnecessary panic among patients and visitors. Perhaps the best known is Code Blue, indicating that a patient is experiencing cardiac or respiratory arrest and requires immediate medical assistance.

While some hospitals use their own custom color codes, Code Blue has become so widely recognized that it now appears frequently in television dramas and everyday conversation whenever someone refers to a life-threatening medical emergency.

14 Surprising Origin Stories Behind State Names In The USA

Image: Pin Adventure Map

Ever wondered where most US states’ names come from? From Native American roots to foreign or made-up words, the stories behind many of them are riddled with surprising historical references. Although the origin of some US states’ names is fairly obvious, many derive from unexpected people or places. The origin of names like Colorado, Montana, or Nevada are easy to infer —especially if you know a bit of Spanish— but many others have Native American origins with intriguing meanings. Some are even derived from fiction. If you ever wanted to know where names like Oregon, Connecticut, or Wisconsin come from, you are in the right place. Enjoy the surprising etymologies behind some of the names that make our country.

Interestingly, for a state whose main economic activity is agriculture, the word Alabama comes from the Choctaw language and can be translated as "plant-cutters" or "vegetation pickers", recalling the farming practices of the Native Americans that lived in this area.

Alaska is a corruption of an Aleut word that means "mainland", but can be translated literally as "the object towards which the action of the sea is directed". This is one of those names that manage to bring poetry into a word as simple and down-to-earth as land.

This one comes from… a Spanish adventure novel! Bet you didn’t expect that. In Las Sergas de Esplandin by Garcia Ordez de Montalvo, a book from the 1500s, there is a fictional place called the "Island of California". Even when the modern state of California is clearly not an island, some die-hard fanatic of the novel decided to bring the name to life here in the U.S.

Derived from the Algonquian word quinnehtukqut, which can be translated as "besides the long tidal river", in reference to the river Connecticut. If you are wondering what the "tidal" part means exactly, this is because the Connecticut River's flow and level are effectively influenced by tides along much of its course. Certainly some amazing insight into the rigorous knowledge of local hydrology that Native Americans managed to accrue over the centuries.

Although the origin of this name is disputed, there are two main theories. One suggests that the islands may have been named after Hawaii Loa, their traditional discoverer. However, others have speculated that it is actually derived from the ancient Polynesian word hawaiki, meaning "place of the gods".

Another crazy one. Although the name was first claimed to be derived from a Shoshone word that meant "Gem of the Mountains", it is highly likely that the word was fabricated by George M. Willing, and meant as a practical joke.

Quite literally, "land of Indians", using a Latin suffix. The word Indians originally referred to the ancient dwellers of the shores of the Indus River, in South and Central Asia.

"Toto, I've a feeling we're not in Kansas anymore!" said Dorothy, from The Wizard of Oz, right after a rampant tornado literally lifted her house in the air and took it to God knows where. Well, this US state’s fame for violent winds predates even the first settlers, since Kansas is a Native American word used by the Dakota, strongly related to the idea of "wind".

This state owes its name to an Iroquoian word that means "land of tomorrow". Quite a blockbuster-worthy movie title, if you ask me.

The origin story behind the name of "The Pine Tree State" is still disputed. However, there are some interesting theories. One states that it derives from "mainland", as a form of distinction from the many coastal islands in the vicinity. Other theories propose that it was named in honor of Henrietta Maria, queen of England, or after the province of Mayne in France.

To the Native Americans that lived in this region, Missouri meant "town of the large canoes", as the Missouri tribes were renowned for their skill in making dugout canoes.

A largely disputed one. Many suggest that the name has Spanish origins, being similar to other words like orejón (meaning "big ear") or orégano, in reference to a type of plant (similar to the Mediterranean oregano) that grows in the southern part of the state.

This is the only state that has a part of its founder’s name in it. It is widely believed that Pennsylvania means "Penn’s Woodland", and was named as such in honor of Sir William Penn, father of its founder William Penn.

This is probably a French corruption of a native Miami word that meant "it lies red" or "river running through a red place", in reference to the bed of the river Wisconsin.
