Abstract: A security partition system for prevention of hijackings on airplanes having a plurality of primary partition housings and a plurality of primary partition units. The primary partition units are stored above the passenger seats and, upon activation, the primary partition units slide out of primary partition housings and create a wall between the seat rows and the aisle of the plane thus confining potential hijackers inside of the aisles. A plurality of secondary partition units could be added to isolate individual rows of seats by coupling secondary partition units to seats and the ceilings above the seats.
