safety is a top priority, you never know when you might get in a low speed collision while flying a jet

To be fair, that thing could probably do a 40 km/h faceplant during take-off or landing.

In which case you might want a full face helmet and some armor. The bike helmet is either pointless in the case of a catastrophic failure or not enough in the case of a survivable accident.

It does hold the gopro pretty well, though!
