sphere was breathable and were reasonably certain that the peoples of the world into whose atmosphere we were dropping were at peace. We went unarmed, just the two of us; it might not be wise to go in force.
We were silent, and I know that Harry Albrecht was as perplexed as I was over the fact that our all-wave receivers failed to pick up any signs of radio communication whatever. We had assumed that we would pick up signals of some type as soon as we had passed down through the unfamiliar planet's ionosphere.
The scattered arrangement of the towering cities appeared to call for radio communications. The hundreds of atmosphere ships flashing along a system of airways between the cities seemed to indicate the existence of electronic navigational and landing aids. But perhaps the signals were all tightly beamed; we would know when we came lower.
We dropped down into the airway levels, and still our receivers failed to pick up a signal of any sort--not even a whisper of static. And strangely, our radarscopes failed to record even a blip from their atmosphere ships!
"I guess it's our equipment, Harry," I said. "It just doesn't seem to function in this atmosphere. We'll have to put Edwards to work on it when we go back upstairs."
We spotted an airport on the outskirts of a large city. The runways were laid out with the precision of Earth's finest. I put our ship's nose eastward on a runway and took it down fast through a lull in the atmosphere ship traffic.
As we went down I saw tiny buildings spotted on the field which surely housed electronic equipment, but our receivers remained silent.
I taxied the shuttle up to an unloading ramp before the airport's terminal building and I killed the drive.
"Harry," I said, "if it weren't that their ships are so outlandishly stubby and their buildings so outflung, we might well be on Earth!"
"I agree, Captain. Strange, though, that they're not mobbing us. They couldn't take this delta-winged job for one of their ships
