Factual error: After loading the bomb, Dern and Keller hijack the blimp. As Shaw watches the blimp heading for the stadium, he spots a helicopter across the field, moving bundles of pipe. Shaw and Weaver commandeer the chopper to chase down the blimp. A major part of the security plan for the Superbowl, was that the only aircraft "trusted" to be allowed to fly within a 100 miles of the stadium are the Goodyear blimp and the Police helicopter. The other helicopter would not have been allowed to fly that day.
Continuity mistake: Near the end, while Kabakov is atop the blimp, he finally attaches the cable hook to the blimp. Just as he wraps the canvas strap around the hook, Kabakov's white shirt is neatly tucked into his pants, whereas in the previous and following shots, his white shirt is fluttering in the wind and we can see his abdomen and back.
