Revealing mistake: As Delta Tango 19 takes off from the airport, there is a shot where it is actually landing. This can be seen from the fact that there is no runway behind them, as it is in front of them.
Visible crew/equipment: At the start of this episode a sniper lowers himself towards the President's window on a rope, watch the bottom right of the screen, you can see a hand lowering the puppet.
Suggested correction: Having re-watched the beginning of this episode several times, I'm still not seeing the hand.
