In addition to VO-67, the 21st Helicopter Squadron, also based out of NKP, had just begun dropping sensors on the Ho Chi Minh Trail. Gen Westmoreland ordered them pulled off that effort and reassigned to the sensor deployment at Khe Sanh.
Here Sgt Terry Bruff, Sgt Jim Henthorn, and A1C Steve Miller prepare sensors for loading on CH-3E's of the 21st Helicopter Squadron just prior to a mission.
On 1Aug68, the 21st, along with all other squadrons and wings formerly known as "Air Commando" became "Special Operations" squadrons and wings.
