It may not have been the first with several features and it may not have been a success but after the rotary wing aircraft most everything else is just variations. 6 engine transport vs 4 engine transport and so on.

Nice one. That is new to me. I can see why you choose the Budd too.

The Caproni-Campini CC.2
On 27 August, 1940, the first prototype was tested for 10 minutes over the Taliedo airfield by the great pilot, Mario De Bernardi (Schneider Trophy winner of 1926, RT). On 16 September that same year it was flown for another 5 minutes, thus undergoing the acceptance flight test in order that the second prototype was upgraded. The latter made its maiden flight on 11 April, 1941. On 30 November, 1941, at 2:47 pm, Mario De Bernardi and Ing. Giovanni Pedace flew the second prototype on an official flight from the airport of Milan Linate and that of Rome Guidonia. After flying over Pisa, they landed at 4:58 pm after covering 475.554 km at the average speed of 217.147 km/h. According to the pilot's wish, the afterburner was never actuated in order to save fuel.
The flight was a tremendous success, so much so that Mussolini personally complimented De Bernardi, and low-altitude flights were made over Rome, preceded by announcements repeatedly broadcast by radio. The event took the world by storm, and no less than 33 countries congratulated the Italian government. These flights were recognized by the F.A.I. (Fédération Aéronautique Internationale) to be the first ever made by a jet. Truth to tell, the plan conceived by the German, Hans von Ohain, and the Heinkel group, whereby the extraordinary He.178 aircraft was flown precisely a year before, on 27th August, 1939, had been kept secret.

The engine designed by Ing. Campini had many other drawbacks. That is, it was heavy and bulky, the type of engine used to drive the compressor was rather complex, the efficiency of the burner was low - although it came close to the best possible performance of the day -, and maximum power was considerably limited. This is why the German design - which came into use when World War II was drawing to an end, is the forerunner of the modern jet engines, while the Italian version has a purely historical value
Ducted fan with three rotors, of which two are rotating, and one is fixed (a "fixed rotor" is a contradiction within itself, RT); burners provide 700 kg thrust; engine of the compressor, 900 hp Isotta Fraschini L. 121/R.C. 40; length, 12.10 m; height, 4.70 m; span, 14.63 m; wing area, 36 sq m; weight empty, 3,640 kg; total weight, 4,217 kg; useful load, 577 kg; maximum speed at an altitude of 3,000 m without burner, 325 km/h; maximum speed at an altitude of 3,000 m with burner, 359.5 km/h; climb, 1,000 m in 9 min. (with burner); maximum altitude attained in the course of acceptance flight tests, 4,000 m.

The Engine of the CC-2 Aircraft
Like a gun, which 'reacts' with a quick backward movement (i.e. the recoil) when a projectile is shot forward at high speed, a jet engine derives its thrust by reaction to its high-speed ejection of combustion products, and by the expansion of heated air, which is pushed out at a higher speed than when the air is drawn in. (After all, ordinary propellers work in a similar way. They accelerate backwards the air mass that moves through their rotating blades.) These introductory remarks are meant to help our visitors gain an insight into the workings of Ing. Campini's thermojet. It is, in effect, to be considered more as a hybrid than as a jet engine proper. An internal combustion engine characterized by reciprocating motion of pistons in its cylinder - in this case, a 900 hp Isotta Fraschini L. 121/R.C. 40 engine - drove a compressor incorporating 2 ducted propellers and a propeller designed to direct the flow and minimize the breakdown of the smooth airflow. A ring of injectors (i.e. the burners) introduced kerosine, whose combustion increased the volume of the thermojet and the exhaust velocity.

What is inovative about building a aircraft out of wood ? It certainly had been done before. The plywood- balsa wood sandwich might have been a inovation, might have been one of it's flaws too. Where did Britain get balsa wood from ?
Hmmm, are you sure it's the wood, and not another aspect of this aircraft that makes you suggest it?Here is my contender for the title.
BBC - h2g2 - de Havilland Mosquito - World War II Aircraft
The DH Mosquito.
Why? because it was built with wood!
The Mosquito may have been the best Schnellbomber, but it certainly didn't pioneer the concept.
