correct ground movement hand signals

[Jim Burrill]

For dusk/night movements, I have three of these Aircraft mashaling wands in the Humber stowage. Also whistles.

The guy in eye contact with the driver has two wands and uses them as expected to show hand directions. The rear guide uses his as so: a steady pointed up is "whatever you have him doing is fine , not about to crunch anything. A down is a "thumbs down" or stop. ALong with a whistle. (even if the driver can't hear it, the director can.) And then pointing sideways indicates which way the back end needs to go.
