19 May 1978 Two mechanics employed by CIPA (Centrul de Instruire a Personalului Aeronautic; Center for Aeronautical Personnel Training) at the Baneasa airport in Bucharest Romania, Viorel Nicolae and George Florescu, stole a Britten Norman BN-2-A27 Islander (YR-BNK). This aircraft had been produced under license by IRMA (Intreprinderea de Reparatii Material Aeronautic; Enterprise for Aeronautical Material Repairement, now called Romaero) and was one of the aircraft of this type allocated to Aviasan, a nation-wide emergency medical flying service. Consequently, it sported large Red Cross signs on the fuselage and wings.
After the Islander took off, a pair of Romanian MiG-21 Fishbeds from the 91st Fighter Regiment at Deveselu were scrambled, but due to a misunderstanding on the radio, they instead intercepted and forced down a Romanian An-2 Colt. Two other Romanian MiG-21 Fishbeds from the 93rd regiment at Giarmata (near Timisoara) did intercept the Islander and order it to land at the Arad airport. However, the MiG-21s were low on fuel and had to return to their base.
The Islander then continued on and crossed Hungary from south-east to north-west before landing in a field in Austria near Vienna. The landing gear was slightly damaged in the off-field landing. Several workers from IRMA were sent to Austria to dismantle the aircraft and it was returned to Romania in a truck. Viorel Nicolae and George Florescu were allowed to apply for political asylum and settled in Melbourne, Australia.
