Dr. Moore's Closing
Dr. Moore continues with a discussion of the use of airplanes in the Antarctic.
"I'd now like to mention a few facts regarding the use of airplanes on our expedition. The use of airplanes in the Antarctic is still very much experimental, and it's success upredictable.
Sir Douglas Mawson, perhaps the greatest living authority on the Antarctic, proposed to use an airplane in the field as early as 1911. He instead discovered in Antarctica the windiest country in the world, and likely kept his craft permanently under cover. He measured the average wind velocity for the year at 50 miles per hour; for hours on end blizzards persisted at velocities greatly in excess of the maximum on the Beaufort Scale, reaching a velocity of 116 miles per hour on July 5, 1913, and maintaining an average velocity of 107 miles per hour for eight hours, jarring even the tightly-bolted timbers of their huts. Gusts approaching 200 miles per hour were reported. Such conditions must beggar the mightiest flying efforts of man.
Of course, we should have no problem at our proposed base which is in a relative place of calm on the continent. The principle risks, as we see them, will arise from storms or from the impossible conditions of visibility met unexpectedly in flight, in landings away from the base, upon unknown ice terrain, and from the difficulty in properly securing the ship against the wind in connection with such landings. A wind velocity in excess of 60 miles per hour is sufficient to give a staionary airplane a true flying speed and at 100 miles per hour, a terrific lift; unless securely anchored against that wind speed, a plane would be instantly hurled aloft and destroyed. This challenge, I believe, can be readily overcome and our pilot, Douglas Halperin, is currently designing a new system of anchor lines and ice anchors.
At this point, Dr. Moore's face and voice become deadly serious.
What uncertainty of the future I share centers principally about the matter of attempting landings away from the main base. Our program demands several such landings. Each of these landings must be attended with great risk, for conditions of visibility in the Antarctic are notoriously bad, ice surfaces are extremely difficult to judge from the air and there will be the constant threat of unseen crevasses. Even less attractive is the possibility of a forced landing.
After a brief pause for emphasis, Dr. Moore smiles and continues.
"But there are reasons for optimism in our expedition. The Byrd Expedition proved that the use of airplanes is feasible in Antarctica and, beyond even the advantages that they enjoyed, we possess three of the most efficient instruments given to the explorer: 1. an improved radio, 2. airplanes with improved capabilities for distance, altitude, and speed, bringing an independence of surface obstructions that vex the foot traveller, and 3. a number of motorized toboggans that were proposed and paid for by our own engineer, Vittorio Liuzzi, and which promise to greatly extend our capabilities on land, perhaps reducing our dependance on dogs and airplanes.
We have reason to hope that we might accomplish much.
These then, ladies and gentleman, are some of the challenges that we have accepted. I hope that I have given you enough information to now better understand the nature of our task, and to perhaps convince you to help us on this historic endeavor.
Thank you."
