Clyde was about Burl's size. He had an engagingly boyish air about him, and Burl took a liking to him. Burl had heard of him before. For the young man, while still a college student, had formulated a remarkable new theory of the composition of galactic formations which had instantly focused the attention of the scientific world upon him. This theory had been taken up by the gray-beards of the scientific world and had survived the test of their debates. Now associated with the great Mount Palomar Observatory, Russell Clyde had continued to build a reputation in astronomical circles. "You're one of the expedition, then?" asked Burl, shaking his hand. The redhead nodded. "Yep. They're taking me as their chief astrogator. And don't think it's because I'm any great shakes at it, either! It's just that I'm still young enough to take the kind of shoving around these high brass figure we're going to get. Boy, have they got it figured!" Burl chuckled. "Ah, you're kidding, Dr. Clyde. You've probably been in on this from the beginning." The other shook his head vigorously. "Nope. It was going to be Merckmann's baby, but when they realize they have a fight on their hands, they always look for young blood. And, say, cut out this 'Doctor' stuff. Call me Russ. We're going to share quarters, you know." "How do you know that?" asked a tall, rather sharp-featured man who had overheard them. "The colonel will assign quarters." "I say he will ... and you can bet on that," snapped Russell Clyde. He waved a hand in introduction. "This is Harvey Caton, one of our electronics wizards." Caton nodded, but before he could continue the discussion, Lockhart rounded them all up, packed them into a couple of station wagons, guards and all, and they were off. * * * * * The next days were hectic ones. By car and plane the group was transferred to the large, closely guarded base in Wyoming where the secret anti-gravity ship was waiting. Burl did not see this ship right away. First, he was introduced to all the other members of the crew, and given a mass of papers to study which outlined the basic means of the new space drive, and which detailed the opinions and suggestions of various experts as to methods of procedure and courses of action. He was subjected to various space medical tests to determine his reactions under differing pressures and gravities. Although it proved a strenuous and exhausting routine, he emerged from the tests with flying colors. The expedition was commanded, as he had known, by Colonel Lockhart who would also act as chief pilot. The famous military flier proved to be a forceful personality with a great skill at handling people. He knew how to get the most out of each man.
