I am a current air cadet and I can't tell you how shocking and upsetting this is.
I've been in contact with a few fellow cadet NCO's and all are equally stunned. The safety instruction video they always show you before flying is always taken a bit light-heatedly, I even admit to laughing at the terrible acting. But it has now made me realise how important that video is.
I will never laugh at it again.
RIP cadets, Venture Adventure.
