Laga Ratica

I am afraid an airplane will crash into the freeway directly in front of me. If there is a plane anywhere near the road I have to keep an eye on it just to make sure it stays in the air. This only happens when I'm on the freeway. I can drive by an airport on a surface street and enjoy watching a huge jet pass overhead but if I'm on the freeway I might even slow down a little just to make sure it passes over the road before I get to it. I have no idea where this fear comes from.
