The first jet plane to fly was in 1939, built by German Dr. Hans von Ohain (1911-1998).  His design for that first successful jet engine was patented in 1934.  However, British Sir Frank Whittle (1907-1996) conceived and patented his concept of a jet engine in 1930, but his aircraft did not become operational until 1941. These two men were ignorant of each other's work in the 1930's, and of course were on opposite sides during World War II.  Long after the war, in 1978, they finally met and exchanged notes, and are now considered to be the co-inventors of jet propulsion.

The first airplanes to actually be produced that used jet propulsion were produced during World War II.  Specifically, they were built by Nazi Germany.  The German government began serious work on jet aircraft in the 1930s because Hitler intended to go to war and wanted to have as many strong weapons as possible when he did.

The first jet airplane was produced in 1939.  This did not work well enough to be used in the war.  It was not until late in the war that a really feasible jet fighter airplane was produced.  This airplane was known as the Messerschmidt 262.  The Germans began mass production of the Me 262 in 1944.

 In October 1910, the Grand Palais on the Champs-Elisee, Paris hosted the second edition of the International Aerospace Exhibition.There were exposed the newest aircraft parts. The most interesting machine, which has attracted the attention of many, was a red plane without propellers . On the metal plate it was written: COANDA-1910. This plane was so interesting not only because it had no propeller, but that it was totally different from what they were called by then "flying". The plane had double wings and a scale of 10.3 m, 12.5 m long, weighing 420 kg and a force of propulsion of 220 kg. The most interesting part of Coanda's plane was the propulsion system, a real revolution in building aircraft engines, which was ment to be the solution of the future. Jet engine, invented and built the first time by Henri Coanda was composed of a four-cylinder piston engine-cooled with water and developed 50 horsepower at 1,000 rpm. This engine-piston was connected to a rod that rotated  the multiplier of revolutions, the movement being transmitted to the compressor to win a rotation of 4000 rpm. Propelling force was 220 kgf, much higher than when the engine-piston was connected to a propeller. Many visitors to the exhibition have been suspicious till an accidental demonstration of Coanda, when, desiring only to check the engine, the plane started to go increasingly faster, until he took flight. Impressed by the flames caused by engine and concerned that he didn't fly a plane by then, but gliders, Henry lost control of the machine, which has lost height and speed until a forced landing. This was the first flight test of an aircraft equipped with a jet engine.

Today Henry Coanda is known for the Coanda effect but he is also the inventor of the jet engine plane .

Henri Coanda jet engine transformed travel forever. The jet engine has allowed billions of people now to do something that was barely thinkable just 90 years ago. Although Sir Frank Whittle may have perfected the jet engine, the credit for the invention of the jet engine goes to Henri Coanda (who invented and designed its fundamental principles).

In 1910 the young Henri Coanda (24 years old at that time) made the first demonstration of the jet engine in Paris at the second International Aeronautic Salon.

Around 1910, the pilots were not instructed how to fly, they had to learn to fly through their own experiences and they had to take their own risks. Yes, it was a pioneering jungle in those days.

On that day (in 1910), in order to make some tests on the jet engine, he put a lot of fuel in the tank of the plain and started doing different tests on the jet engine. His attention was focused on the direction of the hot flame of the jet engine and the adjustments that he could make from the cockpit of the plain. As an engineer, Coanda had very little experience as a pilot (no one at that time had any flight experience of any kind).

Being attentive to the technical side of the jet plain, without his awareness, the first jet plain in the world had taken altitude from Paris into the sky. Only seconds later, his jet engine began to burn the wood plane fuselage in full flight and crashed. From the crash he escaped with some minor injuries to his face and hands. Thus, the jet engine era begins.

Between 1911 and 1914, he worked as technical director of Bristol Aeroplane Company in the United Kingdom, where he designed several airplanes known as Bristol-Coanda Monoplanes. In 1912, one of these planes won the first prize at the International Military Aviation Contest in the UK.

For his successful inventions, Henri Coanda was awarded many distinctions such as Harry Diamond Laboratories Award, Award and Grand Gold Medal “Vielles Tiges”, UNESCO Award for Scientific Research, The Medal of French Aeronautics, Order of Merit, and Commander Ring.

Coanda died in Bucharest, November 25, 1973 at the age of 86 leaving behind 2608 inventions.

Henri Coanda a Romanian Engineer, was the first to build a jet plane in 1910. Later on, two engineers, Frank Whittle in the United Kingdom and Hans von Ohain in Germany, developed the concept independently during the late 1930s. The concept had already been discussed as early as August 1928 by Frank whittle at Flying School, Wittering, but Hans Von Ohain also wrote in February 1936 to Ernst Heinkel, telling him of the design and its possibilities.

The concept of the jet engine was developed during the 1920s and '30s by Frank whittle and Hans Von Ohain. 

Jet aircraft are usually designed using the Whitcomb area rule, which says that the cross-section of the aircraft at any point must be approximately the same as the Sears-Haack body. This minimises the production of shockwaves which would waste energy.

The first jet plane to fly was Heinkel He-78 which was designed by a German physicist Hans von Ohain. The first flight of this plane took place in 1939. This was followed flight of a jet plane named Caproni-Campini CC2 built and flown in  Italy in 1940. However, both these aeroplanes did not prove to be very successful. The first really successful jet plane was Gloster E 28/39 developed by Frank Whittle for the UK. First flight of this plane took place in 1941. The first jet plane in the US was built by Bell Aircraft Company in 1942.
