Isn’t it time we let the past be the past?   Airplane tugs with "form follows function" design should be a thing of the past.   At a commercial level, a quality tug needs not only to be a brute,  with all the power and durability needed for the job, but to also provide feedback and liability diminishing data.   Commercial users want to know how much force was needed to move a plane.   They want to link that to the plane they were moving, where they moved it from and to, who did it and more. Sierra is the future of commercial tugs. Check out the full line of Sierra Tugs for commercial application.   Pre-Orders are being taken now.
