For combined military and civil aircraft operation

A Retractable Hook Cable system reduces the risk for damages on taxiing aircraft and minimizes the wear on the runway surface compared to having a pendant cable installed across the runway with elevators (rubber donuts). A retractable system allows the hook cable to be pre-tensioned in both raised (active) and lowered position (in a groove) below the runway surface. The retractable system is referred to as BAK-14 by the USAF.
