The concern isn't the normal emergency items normally in the vehicle (airborne or other), it's the other stuff that normally wouldn't be there if there wasn't a decided intent to use it during the trip.

I'm very much into survival/preparedness, and am quite aware of gear that stereotypically one would, or would want to, take into a genuine survival situation but in no way would actually haul around on a regular basis for the unlikely chance of actually needing it - stuff that I would be quite suspicious of should the "victim" actually have handy.

For this case, many other comments here are startled about the presence of a full sport parachute, already being worn, during an ostensibly mundane "just traveling" trip ... along with wrist-mounted GoPro, selfie stick, etc.
