What could that mean? Lea and San, passing, but not stopping!

We got transportation down into the city, avoiding the areas where the fighting was raging. An official car took us by devious route to the tower-space. The street here was heavily guarded by the city forces, but the Turberites were fighting close to the south. Only a few blocks away we could hear the sounds of the battle.

The tower had come and passed. Its marked space in the street was empty. Our guards surrounded it. We stood among them.

A phantom showed over our heads! A moving phantom of the Turber aero! It darted across the tower-space and vanished.

Now we understood! San and Lea were trying to land. Bluntnose, with the aero, was endeavoring to prevent them. He had followed the tower through Time. Two speeding phantoms! The aero could wing its way directly through the tower without contact—when they were speeding phantoms! But not if they stopped.

The tower showed again. A brief wraith of it. Just an instant; but in that instant the aero also materialized, circling, darting. Then they both were gone.

Would San dare stop? Would he risk that Bluntnose might wreck the aero and kill himself, just to wreck the tower?

Another moment. Again the phantoms showed. The aero was slightly above the tower, and to one side.

The tower did not pass. In a breath it materialized into solidity before us. My heart seemed to stop. San had dared!

The aero seemed half to turn. And then the wraith of it vanished!
