I've heard of tis before, but I did'nt knoiw how low they went. That has to be one of the most remarkable things in the history of aviation. When I see a C-5 come and go at Elmendorf, I just can't believe they could get down to 100ft. Imagine being in the ground as a C-5, bigger than a 747, passes right over your head, engines screaming! I'd love to fly chase and watch the giant moving along at such a low level. That is simply amazing.
