It was 1941, protagonists were engineer Secondo Campini, Officine Caproni and Colonel Mario de Bernardi, names certainly not unknown in the aviation environment.
And together they achieved a great Italian record thanks to the Campini-Caproni C.C.2 jet aircraft, an elliptical, low-wing monoplane built entirely of duralumin.
After testing in August 1940, the expert aviator Mario de Bernardi did not hold back and, accompanied as a passenger by Cap. Pil. Ing. Giovanni Pedace, on 30 November 1941 successfully completed the first postal jet flight, from Linate to Guidonia in 2 hours, 11 minutes and 24 seconds at an hourly average of 209 km, 451 over a distance of 475 kilometres.
It was the first jet-propelled airplane to make a long flight and, moreover, it was the first jet aircraft in the world to use an afterburner and carry air mail.
