I know that the airlines are all required to put lifejackets and seatbelts and other safety equipment on all planes, but don't most people realize that a lifejacket won't help you one bit if your jetliner crashes into the ocean? A seatbelt really won't help you either, mainly just to keep you in one spot for takeoff and landing. Anyway, here in this section I have seen numerous sections about bringing carseats or other child-safe restraints on aircraft. What is the point of lugging around a carseat on the airplane (instead of checking it in the luggage)? Let's face it--in a plane crash, a car seat isn't going to help.
