Angular Wings
Angular wings came about as the airlines industry was looking for ways to maximize efficiency and minimize cost. The sweeping back of the wings is more fuel efficient and economical, but still stabile with the help of extra flight control surfaces other than the ailerons and flaps. Pictured above is a Boeing 727-100 freighter N190AJ on climb out after take-off. Barely visible on the tops and bottoms of the wings are gates that open and close in flight to assist in maneuvering and slowing down. Below is a sister ship of N.A.C.'s fleet, also a Boeing 727-100, N992AJ
