“Chicken, airplane, soldier” (backstroke swimming)

“Chicken, airplane, soldier” is how many swim instructors explain the backstroke to young swimmers. Hands are under the armpits (like a chicken), then arms are spread directly out (like an airplane), and then arms are brought straight down directly to the body (like a soldier standing at attention).
   
“Chicken . . . airplane . . . soldier” was cited in Froggy Learns to Swim (1995).

Their group instructor, Trisha Becher, taught them the arm movements by remembering three simple words—chicken, airplane, soldier.
 
Chicken means to tuck your hand under your arms, like a chicken would look flapping its wings. Airplane means arms straight out from your sides. And soldier means arms flat against your sides as if you were standing at attention.
 
Put the three together in a fluid motion, throw in a power kick and you’re doing the backstroke.
