There are both compact and bus-size jetplanes. We should make multiple articles about different size jetplanes just like there are articles about different size automobiles. The article I am suggesting are compact jet and commercial jet. -- SuperDude 00:18, 22 Apr 2005 (UTC)

I have searched around and can find no mention of this. Since the shuttle is more or less belly-up during launch, it seems counterintuitive that the lift surfaces would be of any help. In fact, it seems the opposite would be true. I would suggest deletion of this if the author can not provide citation. BigDaveB ( talk) 19:26, 12 June 2008 (UTC)

The history section mentions that the first manufactured turbine jetplane was the Heinkel He 178 turbojet prototype of the German Air Force (Luftwaffe), piloted by Erich Warsitz on August 27, 1939. I've got an article by Sir Frank Whittle here in an old aircraft magazine, entitled 'Contact' The Magazine for Air-minded New Zealand. Feb 1954, which contains a section wherein he discusses this, relating to the question of whether the Germans flew the first jet. He writes that in the sense that they got one off the ground for a few minutes but that if it was a question of the first flight of an efficient and successful airplane then no, and adds that Britain was certainly first in the field. He describes the test flight of the Heinkel on August 27 1939, saying; "A tiny single-seater jet Heinkel -the HE.178-flew for ten minutes in Germany on August 27, 1939, four days before the invasion of Poland. What happened on that flight is a mystery to me; but the engine was not further developed, and the plane never went into production." No mention of the Italian test flight mentioned in this article either, but Frank Whittle would have been aware it, it apparently having been heralded internationally as the first successful jet flight at the time according to the linked article, and may not have counted it as a successful flight for similar reasons to the above. I think it's worth noting in the article, if he's correct, that the Heinkel, while the first manufactured jetplane, was not successful, only flew for ten minutes, and was then not continued. And maybe something similar for the Italian prototype test if details can be determined. Number36 ( talk) 22:44, 19 March 2009 (UTC)

Coanda's 1910 aircraft was an attempt at a ducted fan. He described it as such in painstaking detail in several patents (British patent #GB191112740(A), Swiss patent #CH58232(A), etc). Aviation journals and magazines which covered the air show described it as a ducted fan as well(Cassier's Magazine (1911) Volume 39, page 199; Popular Mechanics March 1911 page 359; Technical World Magazine (1911) Volume 15 page 615; Aircraft (1910) Volume 1 page367). Coanda didn't change his story and start claiming it was a jet until others had invented jet engines; and when did he had a great deal of trouble keeping his story straight. Does anyone really think he should be credited with building a motorjet when there's no evidence whatsoever that he did, and a huge mountain of evidence that he didn't? Romaniantruths ( talk) 23:59, 2 August 2010 (UTC)
If verifiable scources are needed to make an edit, User 79.113.9.72, then I guess I'd better remove the totally unreferenced assertion that the 1910 Coanda was a jet. I know you'll want whoever made those assertions to please understand if we don't take their word for it Romaniantruths ( talk) 18:02, 7 August 2010 (UTC)
The magazines referenced are all public domain and can all be found with a search of Google books. The patents are all also available on the internet, but just to make it easy for you here are some simple directions: Go to the Henri Coanda Wikipedia page and scroll down to the references. Click on The patents of Henri Coanda. Scroll down the patents until you find the patents I specified (the French one is there too! And if you can't read French, I think there's even an automatic translation available). Once you've read Coanda's own description of how his turbopropulseur works and seen his diagrams, please let me know if you have any evidence to the contrary other than his much later unsupported personal assertions, or re-iterations of same by lazy aviation historians. If you do find anything else perhaps we can discuss wether what you found should trump these primary scources in Coanda's own words. Romaniantruths ( talk) 20:26, 5 August 2010 (UTC) And while we're at it, I notice that you've made quite a few edits to aviation articles without references(like the claim on the aircraft engine page that Jatho was the first person to attempt to fly using only on-board means, do you really mean that nobody ever tried this before 1903?). I don't spend a lot of time on Wikipedia so maybe you can explain why these rules apply to my edits, but not to yours.--With warmest regards Romaniantruths ( talk) 20:26, 5 August 2010 (UTC)
I will post some references (there is an abundance of them on "Henri Coanda" and "Coanda-1910" page, and i hope the personal bias of some peoples will not stop to be added
"Romanian inventor Henri Coanda attempted to fly a primitive jet aircraft in 1910, using a four-cylinder internal combustion engine to drive a compressor at 4,000 revolutions per minute. It was equipped with what today might be called an afterburner, producing an estimated 500 pounds of thrust. Countless loyal Coanda fans insist that the airplane flew. Others say it merely crashed."
"The Coanda effect is familiar to most hydraulicians, although perhaps not by name. The effect was first observed in 1910 by Henri-Marie Coanda, in connection with exhaust flow from an experimental jet engine (Stine, 1989)."
And there are more, i dont think is needed to put them all, and is pretty clear by now. So i propose an introduction phrase as:

Even if Coanda 1910 had used just a ducted fan powered by a piston motor, the overall engine fits the definition of a jet engine (see below) and in consequence the picture of the airplane has to be added. Coanda 1910 used oxigen to burn fuel and produced a backward discharge of gases that pushed the plane forward. This is in the definition of a jet engine.
"Definition of JET ENGINE
"jet engine
1. An engine that develops thrust by ejecting a jet, especially a jet of gaseous combustion products.
2. An engine that obtains the oxygen needed from the atmosphere, used especially to propel aircraft and distinguished from rocket engines having self-contained fuel-oxidizer systems."

There is enough power to fly a ducted fan jet engine. If you do not believe just take a look at this aircraft that flew in October 1932. http://en.wikipedia.org/wiki/Stipa-Caproni
"Once again, this article cannot state with certainty that the Coanda-1910 aircraft was the first jet aircraft. Gibbs-Smith and Winter performed extensive historical research and determined that it did not fly, ever, and that it did not have combustion in the air stream, a requirement for flight in air, as without it there would not be enough thrust."(Binksternet) — Preceding unsigned comment added by 70.83.160.23 ( talk) 20:40, 13 March 2013 (UTC)

It was still a start. I didn't even say what it was, I just put the picture and it's name, let the reader decide whether it's a jet or not. It was a precursor. Can you respect that and give it the place it deserves, namely on this page? Romanian-and-proud ( talk) 19:17, 12 December 2015 (UTC)
How do you know it had absolutely no influence? Hm? Can you prove that beyond any doubt? Romanian-and-proud ( talk) 19:41, 12 December 2015 (UTC)
The article claims that "[t]he turbojet was invented in 1939". While the exact date on which the turbojet engine was invented is debatable, it was unquestionably before 1939, since Frank Whittle was testing a fully operational turbojet engine in 1937, having developed his design many years earlier. The article should be updated. BertyRussell ( talk) 12:27, 11 January 2021 (UTC)
There are a ton of bad generalizations and factual inaccuracies. Some parts are good, but others are riddled with typos
Things that I think could be better:
The jet engine section states a rocket engine is a type of jet. This is not true, as jets are fundamentally different in form, performance, and use. According to the Britannica definition, a rocket engine is not a jet because it does not intake air.
The flying characteristics section is a mess. It is only stated that jets preform differently with no further explanation. Jet engine’s response time varies massively between different jets and aircraft, which makes stating that they respond slower inaccurately.
There are several grammatical errors throughout the article.
I.E: The Lockheed SR-71 was one of the fastest jet flying at Mach 3.35 (3,661 km/h (2,275 mph
Mach is used in the article without any mention of the altitude or temperature, which makes the measurement useless as it changes depending upon the situation.
i might add stuff later
