Sleep Eating Chicken Wings After a Long Shift

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

Explaining Nature on Instagram: "Hummingbirds are tiny, fast-moving birds known for their incredible ability to hover in midair by rapidly beating their wings—sometimes up to 80 times per second. They are the only birds that can fly backward and even upside down for short bursts. These birds have brilliant, iridescent feathers that shimmer in the light, and they feed primarily on nectar from flowers, using their long, specialized beaks and tongues. Hummingbirds play an important role in pollinat
