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.
ZF534 was a technology demonstrator that led to the Eurofighter Typhoon and first flew on August 8, 1986. It was retired in 1991 and after 11 years at the Loughborough University, was transferred to the RAF Museum.
There are conflicting stories on D-ICDS. One is it crashed in 1985 and was not repaired. The registration was transferred to the second prototype (CD-2 c/n 1001). Another says it was rebuilt as more representative of the production aircraft. In that scenario, the second prototype (CD-2 c/n 02) was slightly larger and registered D-ICKS. Another source says the aircraft at Paris was the CD-1A c/n 01. That is what has been used here. D-ICDS at Paris 1987 had the shorter fuselage and round windows of the first prototype (CD-1) but the wing and pontoon design of the CD-2.
