Some, but not all, sea planes come with wheels in their floats so that they can work on the water or land. But have you ever thought about how a plane without wheels, water or runway would take off? The answer is incredibly cool to watch. The plane is on a little cart at the back of a truck and speeds down the runway. When it hits take off speed the amazing part happens. The float plane goes from sitting on its little platform to airborne in just a split second.
