After lying in the river, Susie and Don are completely dry in the next scene.
After Don radios the tower for runway clearance to take off, the next scene shows an older, mustachioed man taxiing the plane without Susie by his side.
After Isis puts out the fire there is no soot on Susie's face when she is shown from the side and her hair is over her left shoulder but in every shot from the front she has soot on her face and her hair is tucked behind her.
During the tightest closeup of Captain Marvel on Don's airplane, it is relatively clear that a dummy is fastened to the aircraft and it bobs noticeably in the wind.
