For "AIRPLANE" use a small double motion. You move the hand
forward just a couple inches or so, then bring it back, then move it forward
again. Make sure to angle the palm down a bit so you aren't just signing
"I LOVE YOU."
AIRPLANE:
Note:
The sign "AIRPLANE" when used in context can be interpreted as "AIRFORCE."
