Announcing a new title in the excellent I Can Read Book scries: Beginning readers, especially boys, are indiscriminately fascinated by the people who run things -- whether it is a space capsule or a fire truck. The author capitalizes on this interest by describing the daily work schedules of railroad engineers and airplane pilots. Short, simple sentences describe their training, the equipment they must master and the vehicles they direct. Leonard Kessler's lighthearted sketches are in three colors and picture the items as they are identified with an especially good cross section of the activities of special cars in a train. Special emphasis is placed on how long both the engineer and he pilot must work before they are allowed to take over the most precious cargo -- people -- in passenger trains or planes. A reassuring note in an easy reader by the same team responsible for Doctors and Nurses: What Do They Do?
