While Maisie is flying the helicopter, she is seen flying from the left seat; except for the scenes where she is seen from behind. In the that scene she is clearly on the right side of the helicopter.
Twice there is a close-up of Maisie's hand with nails that have on no nail polish, but Ann Sothern is clearly wearing polish.
While Maisie is in the helicopter flying over the city, the wire holding the helicopter in the air can be seen.
