Snakes on a Plane

I was showing my class pictures of my trip home which included pictures of the plane that I thought the kids would like. Chandrella raised her hand and when I called on her she asked, "Mr. B, have you ever seen Snakes on a Plane?" I told her that I had. "That's why my mom doesn't want to go on a plane!" Now I know the statistics say you're more likely to get in a car accident then be in a plane crash, but I don't know anything about the likelihood of snakes on a plane. So there wasn't much I could say to that...
