The fourth of a series of Navy flying boats built for transoceanic flight, the NC-4 took off from Newfoundland on May 8, 1919, landing at Portugal on May 27, completing the first transatlantic flight. Before the flight, the plane and its crew were in Halifax, Canada, where machinist Pat Carroll wrote a letter to his brother Charles, a corporal with the American Expeditionary Forces in France. Pat asked a member of the NC-4 flight crew to carry the letter and mail it after the flight. When the crew reached Lisbon, Portugal on May 27, they placed that letter in the mail. The letter is now in the collection of the National Postal Museum.
Vezdelety boots, the first iteration of Zimmerman.
Do you know who actually made the first seven-league boots ? True , I mean that ” through the sea, through the woods ?” His name was Charles H. Zimmerman ( Charles Zimmerman ), and he worked at the research center of the U.S. Army in Palo Alto . He mused over the idea even during the Second World War, and by 1948 brought to the metal and test their “flying shoes ” . They represented a motor with two propellers and a platform for standing on her pilot between them. The only controls in the hands of pilots were throttles . Control of the direction and speed of movement performed by the pilot shifting its center of gravity . Zimmerman called it ” kinesthetic control . “
Externally crazy idea placement of the CG above the center of thrust application ( capsize same ) was not so crazy . In fact , such a system in the case of tilting starts to slide in the same direction , and due to the air resistance acting on a vertical shape recovers equilibrium. Or - if the slope is large enough - even starts moving toward displacement DH. That’s the whole principle in general . And if the amount available to the pilot offset DH ( fencing ) is a mere framework - then flying to overturn such a paradox is not easy. High - speed limit to get some flight chosen side .
The aircraft was tested pilot Frank Peterson , but it flew near , a low and not quick . It turned out that just manually synchronize motors hard ( respectively , leads to the side ), and the slightest disruption in the operation of one of the motors - could still make the ” flying shoes ” in Flightless grinder . Therefore , confirming the performance and more than that - an intuitive accessibility for any unprepared person - ” kinesthetic control” , the Americans decided to go to odnosotornym flying platform , first with open propellers , and then screw in the enclosure under the pilot’s legs .

The Lockheed D-21 was an American Mach 3+ reconnaissance drone. The D-21 was initially designed to be launched from the back of its M-21 carrier aircraft, a variant of the Lockheed A-12 aircraft. Development began in October 1962. Originally known by the Lockheed designation Q-12, the drone was intended for reconnaissance missions deep in enemy airspace. The D-21 was designed to carry a single high-resolution photographic camera over a preprogrammed path, then release the camera module into the air for retrieval, after which the drone would self-destruct.
The Anglo-American inventor of the machine gun, Sir Hiram Maxim experimented unsuccessfully with powered flight during much of the 1890s.
In 1911 he established a company to develop military aircraft with Louis Blériot, the first man to fly across the English Channel and engineer Claude Grahame White, one of Britain’s first qualified pilots.
