Signing: To do Airplane, take your outstretched hand and tuck in your middle finger and your ring finger (the two fingers next to your pinky), to make an airplane. Then move your hand away from your body as if flying. Sound effects are optional!
Tucking in those two fingers is often difficult for an infant and you will often see airplane simplified with either all four fingers tucked in, or with all fingers outstretched.
Usage: Airplane is a fun sign that we use in play. Use airplane when you see and hear a jet wooshing past overhead. You can also use it in conjunction with an airplane toy or a book that mentions a plane. Babies boys especially like this sign because it is so animated, and the sign resembles the motion of the actual thing.
