Precisely. Why waste words when sign language will suffice. We practiced close formation flying in the RAAF. The leader would look at you across the wing of his Mustang and make patting movements on top of his head. I think that meant go line astern. A movement of his hand towards his oxy mask indicating a drinking movement meant something to do with needing fuel. A twirling circular wave of his hand when ready for take off in formation meant open the throttle to 30 inches of manifold pressure. A hacking motion shortly after meant let's go. Ah sweet nostalgia...
