Continuity mistake: Gibbs places a stack of photos down on the picture of the captain when speaking to him. When the shot changes, the stack of photos has moved off the photo of the captain. (00:07:00)

Revealing mistake: When the guy tied to the chair falls over, he uses his right arm to break his fall, then places it behind his back again after he lands.
Audio problem: When Tony is speaking with the commander on deck, he says he is waiting for "the next aircraft." But his lips don't match the words. (00:11:46)
Yankee White - S1-E1
Character mistake: The uniform/costume that Major Tim Kerry, a Marine Military Aide to the President, is wearing, includes a Service Aiguillette made of 4 loops of round gold wire and scarlet cord. This aiguillette is worn by a Marine serving as an Aide or in other positions for a 4 Star General. A military aide to the President would wear 4 loops, all gold (as seen being worn by Commander Ray Trapp). (00:29:00)
