What is the primary purpose of a tail walker during towing operations?

The primary purpose of a tail walker during towing operations is to enhance safety during turns. When an aircraft is being towed, particularly larger aircraft like the F-35, the tow vehicle and the aircraft itself need to navigate carefully, especially during turns. The tail walker assists by monitoring the rear of the aircraft, ensuring that it does not come into contact with obstacles or other aircraft, and that the path is clear. This role is vital because it helps prevent accidents and damage that could occur if the tail of the aircraft swings too wide during the maneuver. By providing an extra set of eyes and guidance, the tail walker significantly contributes to safer towing operations.
