More than twenty feet high, the outer fence was buried six feet into the ground and was some hundred yards away from the hangar building itself, and fifty yards away from the second fence. The entire area was also guarded by radar. Should any unauthorized person or object be found in that area, an automatic alarm sounded and in fifteen seconds a hundred fully armed guards were ready for action.
"Alfie's busy with a special scanner, sir, one that's especially sensitive to copper. Since the sun is composed mostly of gas, with this filter only Junior will show up on the screen." "By the rings of Saturn," exclaimed Connel, "you mean to tell me that Alfie Higgins is building a new radar scanner, just like that?" "Why, yes, sir," answered Roger innocently. "Is there something wrong with that?"
Connel smiled. He was reluctant to press for an investigation of the radar deck, knowing that if he did, it would mean a damaging black mark against Manning. But justice was justice, and Connel came closer to worshiping justice than anything else in space! Connel placed the spool of tape in the audiograph and settled in a chair to listen. He didn't like the entire affair.
Several times during the night the targets passed close to commercial airliners in the area and on two occasions the pilots of the airliners saw lights that they couldn't identify, and the lights were in the same spots where the radar showed UFO's to be.
I don't know what it is. Do you understand? The thing is down there in the lake now. Floating. I can see it!" Lockley swallowed. He couldn't believe this immediately. He knew nothing of radar reports or the seismograph record.
Of course, there are daily and seasonal changes, but over limited periods of half an hour or so, the F layer at a given location is actually quite well-behaved. It bounces back signals in a nearly constant direction and with nearly constant amplitude just what is required for good radar performance.
"I'm doing this as much to protect Cadet Manning as I am to prosecute him! I want to be sure there was no connection between the crash of the Annie Jones and his tampering with the radar circuits!" Connel replied. "I guess you're right, sir," replied Stefens. "Those two survivors, Loring and Mason, are having coffee in the mess if you want to talk to them."
Almost every month finds some new development in electronics which must be put into production in order to maintain our technical superiority and in order to save lives. We have to work every day to keep ahead of the enemy in radar. On D-Day, in France, with our superior new equipment, we located and then put out of operation every warning set which the Germans had along the French coast.
As the disrupter beam could be projected only about a mile, they would have to dive down on the enemy at once; an instant later the great plane beneath them seemed to be rushing upward at a terrific speed. The two radar beams were kept focused constantly on the Pirate's craft. When they were about two miles from the two planes, the neon tube blazed brilliantly with a clash of opposing energy.
It was not startlingly intellectual information to be sent out in tiny clicks ranging up and down the radio spectrum. But it was orders. Baird sat with compressed lips. Diane listened for a repetition of any of the transmitted signals, sent back by the Plumie. The speakers about the radar room murmured the orders given through all the ship.
