Other mistake: The crew goes up to Calgary in January to extinguish an oil fire, yet there's no snow on the ground, the grass is green, and all the deciduous trees have leaves.
Continuity mistake: Just after the opening credits, Gregg Parker arrives at a fire site, in a helicopter, with a woman he met on a plane. He has a conversation with Chance Buckman as the rotor on the copter slows down to a near stop. As the conversation continues, they cut to a slightly different shot, with the copter still in the field of view, only the rotor is now turning quite rapidly.
