There was a moment of tenseness between them. The older man's face tightened.
"Are you crazy?" blazed Jeff. "It was here when we came. It'll be here if we leave. Let's get going. We can report it if you want. Let the Federal ships investigate."
"Maybe it just landed," his father said evenly. "Maybe it's in trouble."
"What if it is?" Jeff insisted. "Don't you realize we're a sitting target here? And what do you think it is--Aunt Susie's runabout? Look at it!" And with a savage flip of his hand he shoved the magnification of the viewing screen up so that the other ship seemed to loom up a handbreadth beyond their walls.
It was an unnecessary gesture. There was no mistaking that the lines of the other ship were foreign to any they had ever seen. It was big: not outlandishly big, but bigger than the Emerald Girl, and bulb-shaped with most of its bulk in front. There was no sign of ports or airlocks, only a few stubby fins, which projected forlornly from the body at an angle of some thirty degrees.
And from its silence and immobility, its strange inhuman lines, a cold air of alien menace seemed to reach out to chill the two watching men.
"Well?" challenged Jeff. But the older man was not listening.
"The radarcamera," he said, half to himself. He turned on his heel and stalked off. Jeff, sitting tensely in his chair, heard his father's footsteps die away, to be succeeded seconds later by the distant clumsy sounds of a man getting into a spacesuit. Jeff swore, and jumping to his feet, ran to the airlock. His father, radarcamera at his feet, was already half-dressed to go outside.
"You aren't going out there?" he asked incredulously.
The older man nodded and picked up his fishbowl helmet. Jeff's face twisted in dismay.
"I won't let you!" he half-shouted. "You're risking your life and I can't navigate the ship without you."
Helmet in hand, his father paused, the deep-graved lines of his face stiffening.
"I'm still master of this ship!" he said curtly. "Alien or not that other ship may need assistance. By intraspace law I'm obliged to give it. If you're worried, cover me from the gun-turret." He dropped the helmet over his head, cutting Jeff off from further protest.
Seething with mixed fear and anger, Jeff turned abruptly and climbed hurriedly to the gun-turret. The twin barrels of the rifles were already centered on their target, which the aiming screen showed, together with the area between the two vessels and a portion of the Emerald Girl's airlock, which projected from her side. As Jeff watched, the outer lock swung open and a grey, space-suited figure raced for the protection of the bow. It was a dash of no more than five seconds' duration, but to Jeff it seemed that his father took an eternity to reach safety.
