Well, possible - but then the Red Bull one has set a precedent. It's a lovely heli - one that we Brit heli techs would have given possible even a left wotsit for instead of the Gazelle, but noooo... politics is more important than what us techs think. Even the Eceureil would have been preferable to the Gazelle as far as "soldier proofness" goes. OK, so I loved the Gazelle too in the end...
There's some excellent BO 105 demo videos on YouTube - simple enough to find. Another search term is "Chalie Nagel" - he's the pilot that did most for the BO105 in the way of advertising flying (low, fast, bloody hell, white knuckle stuff)
