An attendant came forward and pointed to the chocks. Jimmy nodded “O. K.” As the attendant pulled the chocks from the wheels, Jimmy glanced at the wind-sock on his hangar. Then he taxied slowly down the field. He headed into the wind and gave her full gun. The ship accelerated rapidly. With a thundering roar the ship took off gracefully, guided by an experienced hand and brain. Jimmy was off on his assignment. He cut over to the very edge of Long Island and followed the southern shore-line. Over the Bay and across the southern end of Staten Island he winged his way, heading south of west, to pick up the route of the Air Mail. Long before he crossed the Delaware, near Easton, he was right on the line. How much like old times it seemed, to be flying over the beacon lights. To be sure, they were not flashing now, in the morning light, but he knew where the towers were and he saw each one as he flew over it, where it stood like a friendly sentinel, to point out the path. In the clear light of day Jimmy had no need of guide-posts or flashing lights or radio signals. He knew the route as well as a schoolboy knows the way to the high school. But Jimmy’s plane was equipped with radio, and ear phones were built into his flying helmet. Presently he “plugged in” to his instrument board to see if he could pick up the weather. That is a topic of constant interest to every flier. He had barely passed Numidia before he heard the Bellefonte radio man sending out his hourly weather report. “This is station WWQ, Airways Communication Station, Bellefonte, Pa., broadcasting weather information on the Chicago-New York airway. It is now 10 A. M. Eastern Standard Time. At Hadley Field, N. J., scattered clouds, ceiling unlimited, visibility eight miles, wind south, nine miles, temperature 50, dewpoint 29, barometer 29.98; Allentown, Pa., scattered clouds, ceiling unlimited, visibility seven miles, wind southeast, four miles, temperature 51, barometer 29.94. Park Place, Pa., broken clouds, ceiling estimated four thousand, visibility ten miles, wind southeast, fourteen miles, temperature 45, barometer 29.89; Sunbury, Pa., overcast light haze, ceiling estimated twenty-five hundred, visibility four miles, wind calm, temperature 50, barometer 29.81; Numidia, Pa., overcast light haze, occasional sprinkles of rain, ceiling twenty-four hundred, visibility three miles, wind southwest, five miles, temperature 49, barometer 29.79. This concludes the broadcast of weather information from station WWQ, Bellefonte, Pa.” “That sounds good to me,” thought Jimmy. “I ought to get over to Ringtown and back to Long Island without having to face any bad weather. I’m certainly glad of it, for I’ll have enough trouble as it is.”
