A method and apparatus for controlling aircraft airflow. An apparatus in accordance with an embodiment of the invention can include an air scoop having an inlet and an outlet and configured to mount to the aircraft and be movable relative to at least a portion of the aircraft between a first position and a second position. The air scoop can be oriented to capture air when in the second position. The outlet can be configured to be coupled in fluid communication with a pressurized portion of the aircraft when the air scoop is in the second position to convey air from the inlet to the pressurized portion. The air scoop can be configured to significantly increase the drag of the aircraft from a first value when the air scoop is in the first position to a second value when the air scoop is in the second position.
