Saw a slick move with the crane at the riverside project

They were lifting concrete panels for the new flood wall. The operator had a spotter using colored flags for each direction, which was new to me. It looked way smoother than just hand signals. Could be a good idea for sites with lots of background noise.

Saw airport ground crews use light wands similarly.

Good catch, @carr.amy. It's easy to see how they could be confused.

But aren't those wands for safety, not like what we're talking about?
