The event was opened at 7am by Defence Minister Tibor Benkő and Hungarian army chief Romulusz Ruszin-Szendi both on Saturday and Sunday, the ministry said in a statement.

In addition to presentations by the air forces of Hungary and several foreign countries, the programme included surprise events including a parachute jump performed by the defence minister, the army chief and other army leaders from a helicopter.

A family of military handguns developed fully by Hungarian engineers was also presented.

Visitors also had a chance to see the cabin of Soyuz 36 in which Bertalan Farkas, Hungary’s first cosmonaut, travelled back to Earth on a space mission in 1980.
