Three drunken sailors

I picked up three drunken navy guys from a bar, and it quickly became apparent that two were together, and the third guy, far and away the most drunk, was on his own. He was also incoherent and looked on the verge of passing out. I asked the other two if they minded sharing a cab. They didn't. The next puzzle was the third guy's destination.

The two were going out to Coronado where they're stationed on the U.S.S. Lincoln (Nimitz class aircraft carrier in from Washington). They ended up getting out the guy's wallet and finding his military ID card. It said "72", which is the Lincoln's CVN number. So off we went.

I got them to the Lincoln and cocked my head a little to wait for the fare. Instead, they got out and one of them came to my window and paid. I thanked them and left. Halfway back to the Coronado Bridge, I heard some groaning from the back seat. The super drunk guy never got out! I thought he had. I had to bring him all the way back onto the base and to his ship. After some yelling to roust him, he stumbled out to the waiting arms of the MAs (Master at Arms, navy security).
