When you enter the flight deck from the Tower 1 gangway (bridge), go straight ahead toward the aircraft on display behind stanchions. Turn right and go straight ahead between the two rows of aircraft (airplanes on your left and helicopters on your right). When the aircraft displays end, the Island will be on your left. The entrance to the Island and the navigation bridge is halfway down the structure. You will have step through raised oval-shaped doorways nicknamed knee knockers and climb two flights of steep narrow staircases known as Navy ladders to the flag bridge. This is a one way experience that continues down a flight of Navy ladders to the navigation bridge and then back down to the flight deck.
