One instrument being explained to us is what we might call an all-seeing eye which is part of the radar equipment as we know it. This 'eye' can see for five thousand miles ahead and can detect any kind of storm, any object, or any elemental condition that might be approaching in space, including heavy fog which it can also penetrate. There are four engines each of which resembles a machine gun more than anything else. The jets which are the exhausts are large and these also resemble the barrel of a gun. The pilot touched a button on the instrument panel and started the motors. When these were in operation we could scarcely hear them, they were that quiet. The chamber, which resembles the chamber of a machine gun, is a large cylinder type, yet very small in comparison to the rest of the ship. This cylinder, we are told, contains pellets about half the size of a pea. Once getting into the main chamber of the engine these pellets explode and propel the ship. Each one of these cylinders carries enough fuel to propel the ship for three rounds trips from Mars to the Moon and back. Yet the weight of the fuel for all four engines, according to our weight, would not be more than five hundred pounds. We were curious to know if these weren't some sort of atomic power pellets, telling them that on Earth we have just come into some knowledge of atomic power. They understood our questioning and indicated in the affirmative endeavoring to give us a full explanation of the combustive action and its resultant power, but we were unable to completely understand the details. From what we could get, the action within this chamber is similar to the cyclotron, very small but powerful. Then Bob wanted to know if they used all four engines all the time while travelling. "Yes," answered the pilot. Then he called our attention underneath the ship where there are what we would call stabilizers, six of them in all, that permit the ship to stand in space. After thus looking over the ship, our friends asked if we would like to take a little flight in this giant. George eagerly accepted the invitation for all of us including our Moonalite companions, for we have been wanting to do that very thing ever since we first saw the ship land in this city on the Moon. We are in the air now and the takeoff was so smooth that we didn't realize we were leaving the ground. One outstanding fact we notice, there isn't any vibration like most ships have. It is just like gliding. There were some heavy clouds drifting over the airport and the pilot pulled right into them. We felt no effect within the ship whatever and we have come out of the clouds directly over the city.
