Invented respirator: death due to lack of oxygen
In 1772, the Frenchman Sewell Fleminger invented a recirculating re-breathing device for diving, allowing the exhaled gas to circulate. This is the world's first self-sustaining breathing apparatus. Unfortunately, Fleming's device is flawed. After sneaking into the water for 20 minutes with his invented respirator, he eventually died of hypoxia.
Oxygen re-breathing device: inhaled pure oxygen.
In 1876, the British Henry Fryes invented a closed-circuit oxygen re-breathing device that used compressed oxygen instead of compressed air. His invention was originally used to repair the iron gate of a flooded vessel. Later, he decided to dive with his own invention, reaching a depth of 9 meters. Unfortunately, Frye eventually died of inhaling pure oxygen. Under pressure, oxygen becomes a poisonous gas to the human body.
Wearable parachute: unfortunately killed.
On February 4, 1912, Austrian-born French tailor, inventor and parachute pioneer Franz Ritchett jumped from the Eiffel Tower to test his design of a wearable parachute. Despite repeated dissuasion by friends and viewers, Richter insisted on his own opinion and finally jumped off the Eiffel Tower. Unfortunately, the parachute did not open, and Ritchett paid a living price for his own adventure.
Alcohol powered rocket car: Explosive life.
On May 17, 1930, the Austrian rocket pioneer Max Warrior died in an accident when he tested the alcohol-powered rocket car he invented in Berlin. In 1928 and 1929, Warrier worked with the German Fritz von Opel to create a large number of rocket-powered cars and aircraft. In the late 1920s, he began to focus on the development of rockets using liquid fuel. On January 25, 1930, he first tested liquid fuel at the Highland plant and succeeded.
Shock absorption barrel: died
Karel Susek is a Canadian professional stuntman who invented the so-called shock absorber barrel. On January 19, 1895, Susek persuaded a company to fund him to perform a shock-barrel stunt show at the Houston Arena in Texas. The Dome Gymnasium has a waterfall that is 55 meters high, which is where Susek performs. Unfortunately, Susek did not fall into the pool below, and then slammed into the ground, and died the next day.
Vulku II aircraft: crashed in the fuselage
On September 13, 1913, Romanian engineer, inventor and aircraft manufacturer Orel Vulku crashed into the fuselage while driving his own aircraft, the Volk II, flying over the Carpathian Mountains. Vulku made the flight to become the first person in the world to fly over the Carpathian Mountains. In 1912, Vulku won a series of awards at the Aspen Air Show for his precise landing, throwing and surrounding pillars.
Manual submarine: sinking into the water
On October 15, 1863, the 40-year-old Confederate engineer, Horace Lawson Hanley, died in the hands of his handcrafted submarine, and his body sank into the Port of Charleston, South Carolina.
Hot air balloon: Explosion
On June 15, 1785, Jean Vlass Pilat de Rozil, a French chemist and physic professor and one of the first aviation pioneers, died of a sudden ballooning and explosion of a hot air balloon. At that time, the balloon of the hot air balloon did not catch fire and finally fell near Wimler in the Calais Strait. The flight to Drozl aims to fly over the English Channel.
Rotary press: stuck in your own leg.
On April 3, 1867, the American inventor William Brock, a rotary press invented in 1863, revolutionized the printing industry with excellent speed and efficiency – improving the new printing machine he invented. When trying to put the belt on the pulley, his leg was stuck in the press, causing serious injury. A few days later, gangrene appeared at the wound. On April 12, Brock died in an amputation operation in Pittsburgh, Pennsylvania.
Hang glider: Falling dead.
On August 10, 1896, German aviation pioneer Otto Lilintal tested the hang glider he invented in the Lechno region of Germany. The first few test flights were successful, with a flight distance of 250 meters. During the 4th flight, Lilintal’s glider malfunctioned. He kept swinging his body and tried to adjust the height of the glider, but eventually failed. Finally, he fell from a height of 15 meters from the ground and fell into a serious injury.
