That's like comparing oranges to apples. And planes, indeed fly over your head all the time; there is probably hundred of thousands of them in the air as we speak - how many of them are falling on your head?

If I have a choice of an autonomous emergency parachutte -deployed landing done by my mid-air broken aircar, and being stuck in the heart of Earth with no air and very high temperature literally feeling like a needle in someone's body, I chose the falling cars.
