Kim is at one point asked if she would like to speak to The Unit chaplain, to which she responds by asking what denomination he is. Later in the season while the team undergoes SERE School, she reveals that she lost all faith in God following a miscarriage she had before Bob was selected to be a member of The Unit, so she likely would not have cared about the chaplain's denomination.
In the beginning of the episode First Responders, when we see the aircraft firing an Air-to-Ground missile, the internal view is from the inside is of an F/A-18 Hornet but the external view is of an F-15.
The hijacked aircraft's external and internal appearance do not match. Externally the aircraft appears to be a Boeing 727, with rear air stairs and three rear-mounted engines. Internally however it is depicted as a twin-aisle wide-body jet with seven seats abreast. The 727 is a single aisle narrow-body with six seats abreast. Most wide-bodies don't have rear air stairs, with the exception of the Lockheed Tristar, which has wing-mounted engines and a different seating configuration.
