This is my Uncle Ralph Hansen.  He was commissioned a Second Lieutenant in the United States Air Force.  He earned his wings at James Connally Air Force Base in Waco, Texas after completing Navigation Training.  He served in Vietnam as a Sky Spot Controller.  He used a system called "combat sky spot" bombing system which enabled a ground radar control to direct the bomber over the target and also indicate the exact moment of bomb release in almost any kind of weather.  He was also a Briefing Officer in the SAC (Strategic Air Command) Command Post at Ton Sonute AFB near Saigon, Vietnam, for the General Officers.  After 20 years of service, my Uncle Ralph retired as a Major.   

Thank you Uncle Ralph for your dedicated service!
