We were very lucky to have Heliswiss/Cineflex Europe sponsor us with 3 hours flight/record time. I'm the airshow coordinator, but my company does video production as well, so we made this short video for free in order to promote the airshow.
As for the performers, most of them had nothing against the helicopter as long as it was well over/below their box (6500' for Asas de Portugal, 4000' for Patrulla Aspa, and so on). The problem was with the permits, which weren't issued in time. Hopefully next year we'll have that solved and we'll be able to broadcast the whole airshow live.
