Early on in the 2 and half minute mark you see a young man with a blue shirt sitting across from a red haired woman with a plaid shirt on. But early in the 6 minute mark you see hes across from 2 passengers a young man and woman and the red headed passenger is one row ahead of him.

In defense of First Office Ouimet, the Pilots Association signs a petition that is presented to the NTSB as part of the accident investigation. In a close up of the petition, the address of one of the petitioners/Pilots is listed as "12 in. Penis". It is unknown if this is a fake petition prop created by the production team or if this is a page of the actual petition.
