There was a guy with the Boeing Employee Airplane Modelers club that had a train wreck of a model that he would take to schools and fly at assemblies. He’d break it, stick it back together, and fly it to show that flight didn’t require perfection.
This turkey vulture agrees with him. Perfection is reserved for God.
We call these army ducks. They may be grebes, although they look a little small. They swim down together and, I imagine, do damage to whatever they prey on. It’s fun to watch their perfect surface-dives as they leap completely out of the water. We also saw one duck that worked alone (probably Force Recon or Rangers). He would swim right next to the boat, then dive and work the bottom by himself. Pretty cool to watch..
