A young girl wearing a light blue dress and a young boy wearing navy pants and a yellow shirt walk up the steps to the cockpit of an airplane sitting in the field of an aviation museum.
A brother and sister are walking up the steps to an old silver airplane.
We don't know if the young girl and young boy are related as brother and sister and we don't know that the airplane is old or silver.
