How Things Look on Instagram: "High temperatures have a powerful effect on the Earth’s systems. When the atmosphere warms, glaciers and polar ice begin to melt at faster rates, leading to rising sea levels. This change can flood coastal areas, erode shorelines, and disrupt habitats for wildlife and people alike. Warmer conditions also alter rainfall patterns, causing some regions to experience more intense storms while others face long droughts. Heat also stresses ecosystems and the plants and a

SKY FIGHTERS CLUB on Instagram: "General Dynamics' F-16XL was a study in efficient geometry, a cranked-arrow "big" wing stretched the F-16's planform to gain lift, fuel and payload without redesigning the entire airplane. Two prototypes flew (first flight 3 July 1982), proving a much smoother, high-speed ride and far greater payload-range flexibility than the baseline F-16. Aerodynamically the XL delivered measurable gains, about a 25% improvement in lift-to-drag ratio at supersonic cruise and m
