This is a "turboprop" plane. These smaller planes are just for "commuter"flights. For example, people who live in Swaziland can work in Johannesburg easily enough -- only 45 minutes by plane.
There is a short video attached to this, which shows you how noisy (and fun!) these small planes are. There is a second short video which is from the inside of the plane and shows you the Swazi landscape as the plane comes down.
JOURNAL ASSIGNMENT: For your science/math studies, find out how an engine works. Compare the two engine systems in a 747 (long haul plane) with a turboprop (short distances).
