we had a FAA approved kids seat and a special helmet-ANR-construction from my best half life as a helicopter paramedics.
Could you share details please? What child's seat and which ANR headset concoction?
For the rest it strikes me that many report what they did and how well it went, but as yet I saw no report of anything going wrong, and how. Yet there must be such stories. I would (emotionally) love to take my grandsons up but feel (brainwise) very hesitant.
