9/11 Related Question: Does anyone else get at least a little paranoid when you hear a plane nearby?

That's sad, huh? Ever since the 9/11 incident happened I get a little paranoid when I hear a plane fly around my area. I don't react as bad as I'm making myself sound, haha, trust me. But I do sharpen my hearing and awareness when I hear one. Does this happen to anyone else too? By the way, I'm not sick, or depressed and looking for help. I'm just curious if anybody else gets a little like this too. I appreciate any personal experiences guys. Thank you. Again, I'm FINE guys, haha.
