“Burning 2000 people took about 24 hours in the five stoves. Usually we could manage to cremate only about 1700 to 1800. We were thus always behind in our cremating because as you can see it was much easier to exterminate by gas than to cremate, which took so much more time and labor.”

Blood at Babii Yar - Kiev's Atrocity Story (1943)
Context: At the wide shallow ravine, their valuable and part of their clothing were removed and heaped into a big pile. Then groups of these people were led into a neighboring deep ravine where they were machine-gunned. When bodies covered the ground in more or less of a layer, SS men scraped sand down from the ravine walls to cover them. Then the shooting would continue. The Nazis, we were told, worked three days doing the job. However, even more incredible was the actions taken by the Nazis between Aug. 19 and Sept. 28 last. Vilkis said that in the middle of August the SS mobilized a party of 100 Russian war prisoners, who were taken to the ravines. On Aug. 19 these men were ordered to disinter all the bodies in the ravine. The Germans meanwhile took a party to a nearby Jewish cemetery whence marble headstones were brought to Babii Yar to form the foundation of a huge funeral pyre. Atop the stones were piled a layer of wood and then a layer of bodies, and so on until the pyre was as high as a two-story house. Vilkis said that approximately 1,500 bodies were burned in each operation of the furnace and each funeral pyre took two nights and one day to burn completely. The cremation went on for 40 days, and then the prisoners, who by this time included 341 men, were ordered to build another furnace. Since this was the last furnace and there were no more bodies, the prisoners decided it was for them. They made a break but only a dozen out of more than 200 survived the bullets of the Nazi tommy guns.

Context: Herr Otto Lilienthal seems to have been the first man who really comprehended that balancing was the first instead of the last of the great problems in connection with human flight. He began where others left off, and thus saved the many thousands of dollars that it had theretofore been customary to spend in building and fitting expensive engines to machines which were uncontrollable when tried. He built a pair of wings of a size suitable to sustain his own weight, and made use of gravity as his motor. This motor not only cost him nothing to begin with, but it required no expensive fuel while in operation, and never had to be sent to the shop for repairs. It had one serious drawback, however, in that it always insisted on fixing the conditions under which it would work. These were, that the man should first betake himself and machine to the top of a hill and fly with a downward as well as a forward motion. Unless these conditions were complied with, gravity served no better than a balky horse — it would not work at all...
We figured that Lilienthal in five years of time had spent only about five hours in actual gliding through the air. The wonder was not that he had done so little, but that he had accomplished so much. It would not be considered at all safe for a bicycle rider to attempt to ride through a crowded city street after only five hours’ practice, spread out in bits of ten seconds each over a period of five years; yet Lilienthal with this brief practice was remarkably successful in meeting the fluctuations and eddies of wind gusts. We thought that if some method could be found by which it would be possible to practice by the hour instead of by the second there would be hope of advancing the solution of a very difficult problem.
