Kako je došlo do toga da se u avio-komunikaciji koriste izrazi rodger za "primljeno" i may day kad krene panika?

Ne bih znao da tacno odgovorim za ono prvo ali znam da je izraz may day tek pre neku godinu zvanicno uveden u upotrebu iako je paralelno neko vreme koriscen za SOS-Save our souls. Sad je SOS izbacen a koristi se may day...

Mayday: Used for declaring emergencies, the term is said three times. 'Mayday Mayday Mayday' signifies 'grave and imminent danger,' and comes from the French M'aidez meaning 'help me.' Mayday is the voice term, SOS in used in writing or Morse.

Roger: Etymology: from Roger, former communications code word for the letter r-- used especially in radio and signaling to indicate that a message has been received and understood

Citat:

"Unless you are a licensed radio operator or nautical or flight officer, never use the keyword "MAYDAY" unless you are aboard a vessel or aircraft which is in immediate danger of sinking or crashing! You may endanger the lives of rescuers tens or hundreds of miles away if you do. People in helicopters and other aircraft will respond to a MAYDAY call with limited fuel supplies and risk crashing in order to pinpoint your location! This has caused fatal crashes several times in open ocean and in the Canadian and Alaskan outback."
