On August 27, 1940, the Italian Caproni Campini N.1 took to the skies thus becoming the first jet airplane to fly, or so it was thought at the time.
Today we know that the first jet aircraft to fly was the German Heinkel He 178, having done so on August 27, 1939, but because Heinkel kept it a secret -even from the German authorities- the Caproni took the podium, even if only for a moment.
Although called a jet, the Caproni N.1 propulsion system was actually a hybrid between a piston engine and a jet engine as it had a piston engine that drove a fan compressor system with ignited fuel for added propulsion.
The Caproni Campini N.1 was considered revolutionary -at least in Italy- but its performance was far from being impressive. With a maximum speed of only 233 mph (375 Km/h) it was slower than a Fiat C.R.42 biplane. It was also heavy and had isolation problems which caused the cockpit to overheat, hence why we see the crew flying it with the cockpit open.
Nevertheless, Il Duce saw in it an opportunity for publicity and a year later, on November 30, 1941, a second prototype did a highly publicized 168-miles flight from Milan to Rome where it did a flypast for Mussolini himself. The average speed of the flight was 130 mph (209 Km/h)
By November 1941, both Great Britain and Germany had already come forward with their own designs for more advanced turbojet aircraft. This fact allied to Italy’s dwindling economic and industrial capacity condemned the Caproni Campini N.1 to be nothing more than a mere technological curiosity. Nevertheless, it was still a step in the right direction and for this, it deserves to be remembered.
One of the prototypes survived the war and can be seen today at the Italian Air Force Museum in Vigna di Valle near Rome.
