Low Altitude Parachute Extraction System (LAPES) is a tactical military
airlift delivery method where a
fixed wing cargo aircraft can deposit supplies when
landing is not an option in an area that is too small to accurately
parachute supplies from a high altitude. This method was developed by the
US Military in
1967 during the
Siege of Khe Sanh in the
Vietnam War. It involves loading supplies on a special
pallet on a plane. Once a plane reaches the desired drop point, the pilot descends to a very low altitude of typically under 2 m. Once achieved, the cargo hatch is opened and the extraction parachute is deployed; once the parachute catches the wind outside the craft, it pulls the connected supplies out of the plane and on to the ground. Once the delivery is accomplished, the pilot ascends to a normal altitude and returns to base.
