The pope’s encyclical on climate change is entirely different from what the media reports might lead one to believe. Instead of a narrow and focused contribution to the climate debate, it turns out to be nothing less than a sweeping, radical, and highly persuasive critique of how we inhabit this planet—an ecological critique, yes, but also a moral, social, economic, and spiritual commentary.
The Wrights’ first aircraft, really a large kite, was made of bamboo and paper and had two wings, one over the other, with struts and crisscross wires connecting them. A system of control cords enabled its flight to be directed from the ground. Although they ended with a crash, the tests were successful, the brothers felt, and the following summer they built a full-sized glider with an eighteen-foot wingspan meant to be flown as a kite and, if that went well, to carry a man.
