“How could a 777 follow another Plane so closely without Wake Turbulence being a Factor.?”
Excellent question, Mr. Linville. The vortices coming off the wingtips travel out and down. You would be out of the vortices if you were directly behind or slightly above the preceding aircraft.
Stepped down and in tight would work, as well. Like aerial refueling. Stepped up would make it hard to see the aircraft you are flying form on.
