On the last weekend (15-16th of June), there was a very big
Airshow in Bad Vöslau, Lower Austria,
https://airfest.at/teilnehmer-airshow. In between the T-28 Trojan, Delphin
Jet, and Red Bull Blanix.

We (from http://www.acroproject.at/the-project/) performed the very first aerotowing
on this historical airport. Also the very first hang gliding display was shown
there:

an amazing weekend where we could present this great sport hang gliding to the
crowd.
