Originally named the PD.808 Vespa Jet the business jet was designed in a joint venture between Piaggio and the Douglas Aircraft Company. The basic design work was carried out by Douglas and the prototype was built at the Piaggio factory at Finale Ligure.
The PD.808 was a low-wing cantilever cabin-monoplane with tip-tanks and powered by two rear-mounted Bristol Siddeley Viper 525 turbojets. It has retractable tricycle landing gear and was originally designed with a cabin for a pilot and six-passengers.
The company tried to interest commercial operators (including offering a General Electric CJ610 variant) but the only interest was from the Italian Air Force as a liaison, training and radar calibration aircraft with an order for 25. The Italian Air Force aircraft were powered by Viper 526 turbojets.
On 18 June 1968 one of the demonstration aircraft I-PIAI crashed in bad-weather when it flew into the side of Mount Jaizkibel, near San Sebastian, Spain, all six on-board including the Italian businessman Lino Zanussi and the Piaggio chief test pilot Davide Albertazzi were killed.
