A certain ship needed water and went up- to land.
Usually several were lost when the ship went into action.
Now we are pretty sure where the ship will go.
If she died, the computer and ship went with her.
The central question is not why did the great ship go down?
We've got to get this ship going the right way.
We are at full power just to keep the ship going in a straight line.
The ship goes to sea about three times a year, usually for just a day.
Then that same ship was going to go right back to Earth for more.
Plan that as if the ship might go at any time.
