Aviation incidents are lower than automotive incidents per person-mile. The standards by which pilots are trained far exceed the standards to which drivers are trained. And the vehicle maintenance standards are infinitely higher. Incidents do happen, and when they do, they become newsworthy (because the news loves a spectacle) and this creates a bias in perception of safety.
Humans are notoriously bad at assessing risk using gut feeling, so don't feel bad about feeling bad. But maybe take it as an opportunity to learn about their hobby. If you're afraid of flying, see if you can join them in a simulator or training cockpit just to hang out and learn. The less magical it becomes, the more confident you'll become that they'll be safe.
