By May of that year, a 16,000 square feet plant and a 19,000 feet airstrip was completed, and work on the prototype of the new craft had commenced.
On 15 April 1965, the first prototype took off from the strip at Seven Hills. An elated, yet apprehensive Belgiorno-Nettis declared to the Press: "We have already made a plane, the Airtruk, which looks like a baby elephant... I have sunk a quarter of a million pounds into the plane. I want it out of the red".
