OH-VTP was the third turboprop development of the earlier Vinka trainer. A small production run followed for the Finnish air force and there were exports to Mexico and Eritrea. The project was abandoned and sold to Aermacchi in 1996.
The prototype TB-30 Epsilon was fitted with a Turbomeca TP 319 Arrius engine as the TB-30TP. No production resulted so it was further modified as the TB-31 Omega (registered F-WOMG) with ejection seats under an enlarged one-piece canopy. In this form it was offered to the USAF but lost out to the Raytheon Texan II. F-WOMG has been preserved at Tarbes-Lourdes-Pyrénées airport.
The prototype A320 F-WWAI was the star of the 1987 show after making its first flight earlier that year. It even received a presidential visit from François Mitterrand. F-WWAI's test flying with Airbus finally ended in 2016 and it was repainted in the livery it wore on its first flight. It is to be preserved.
