NASA's Ingenious Fuel-Saving Trick Saves Billions of Gallons

NASA's winglet technology, inspired by bird feathers, has proven to be a highly effective innovation in commercial aviation. Since their introduction in the early 1990s, winglets have been installed on approximately 10,000 jets, resulting in a 6-7% increase in fuel efficiency and saving over 10 billion gallons of fuel. This has also led to a reduction of more than 130 million tons of CO2 emissions, making winglets a significant contribution to environmental sustainability in the aviation industry.
