Planning to go but there are 'difficulties' in the logistics for foreign [non-EU] visitors that may work against the event. They may yet get in my way.
There is a significant charge to enter, to be added to travel and accommodation, which may deter many even though an entry charge is not unusual in Europe as well as the HAI Heli-Expo.
The big plus for the event is that it is pretty much the first real event in the sector for two years!
