Patzer

Whilst being chased by a bull, Fathom falls down at least twice. The first time, her underwear is black. The second time, her underwear is white. The third time, her underwear is brown.

A jumper in competition would have more than one parachute in case one is damaged or if there isn't time to pack between rounds. It would not be unusual, and certainly not a goof, to be packing one parachute in the opening scene and opening another later in the movie.

In the opening scene of the film, Fathom packs her red and white parachute very carefully. She then jumps from the plane, performing some maneuvers an opening her parachute, which has now mysteriously changed to red and yellow.

As Fathom attempts to get behind the controls of the red plane her parachute disappears, then reappears, then disappears again.

After taking control of the plane, it is shown in a steep dive with a left spin. Peter gives Fathom instructions to turn the "wheel" HARD LEFT and pull back on throttle. She's already in a left spin, turning the yoke "HARD LEFT will only increase the spin rate. Next he says, push FORWARD (on the yoke) don't be afraid of diving... she's already in a dive, there is no need to increase speed at that point. Pushing forward helps recover airspeed and prevent stalling. It doesn't help when already in a dive.

In the first moments of the shot where Fathom walks down the steps in her bikini, she is standing still on one step, and the people below are also standing largely motionless, all obviously awaiting their cues to start the action.
