When was the parachute invented?
Have you ever felt like jumping out of a plane? Plenty of people have, but (THANKFUL) most of them did it after parachutes had been invented. Leonardo da Vinci made the first real studies of flight in the 1480s. He had over 100 (DRAW) that illustrated his theories on flight. He designed a parachute in the 1480s, though he didn’t try it out. Another inventor, Faust Vrande, jumped using a similar design in 1617. In 1783, around the same time as the first hot-air balloon, Sebastien Lenormand invented a parachute, which he demonstrated by jumping from a tree, but it was only four meters high. A few years later, having refined his design, he made a (SUCCESS) jump from a taller tower. In 1785, Jean Pierre Blanchard used a dog to test his parachute design. The dog was fine, and so was Blanchard when he used the parachute in 1793 to escape a balloon accident. These early parachutes didn’t catch on because there weren’t any flying machines around to make them (REAL) useful. The invention of airplanes has made parachutes important. Since then, their (EFFECTIVE) has been proved many times.
