Tigner directed Eastern's pilot to enter a left-hand traffic pattern, go counterclockwise around the airport and land on runway No. 3 into the northeast wind. The transport snored steadily in on the prescribed course. Then the Bolivian pilot in the P-38 called in on another frequency and also asked the tower for landing instructions...
Wheels Down. The young traffic controller looked into the sky over the distant roofs of Alexandria, southeast of the field, and saw the fighter circling at 5,000 feet. He switched to its radio channel, told its pilot too to circle the field in the left-hand traffic pattern. He got no acknowledgment. As the transport began its final turn, the men in the tower saw a fearful sight-the fighter, wheels down, was streaking straight in for the same runway on which the DC-4 was about to settle down...
...apparatuses which would be worn, perhaps, on the head, through which controlled and meaningful signals could be sent electrically to the brain of a blinded man. A group of electrical contacts touching the surface of the subject's brain, says Dr. Krieg, might enable him to read. A pattern of such impulses coming through the electrodes of the apparatus might be controlled to appear as words, moving across the blind man's visual consciousness like the letters of an advertising sign...
From here the "last" and the measurements are consulted in making a pattern for cutting out the leather uppers. The trigonometry involved would do credit to a Math 1 student. At this point, Mama's work begins; she cuts and sews the uppers to the required size. The selection and cutting of the upper is a difficult process, since all leather will stretch in one direction. The problem is to select a piece of leather with the minimum of stretch, and then cut it so that the stretching will be in the least detrimental direction...
When the uppers have been cut and sewn, they go, with the "last" and the original pattern, back upstairs. Here Peter, or one of the boys, performs the strategic steps in boot production. The inner sole is tacked to the bottom of the "last" and then trimmed to fit it perfectly. Next, the upper is fitted to the "last" with repeated stretching and tacking. From there, the steel sole shank and outer soles are applied and the heel is built up. Finally a corrugated rubber outer sole is applied and the finishing touches of grooving the heels and waterproofing...
