631st Tactical Control Flight (Source: Paul Costinett) This is the shot of the final cadre of the 631st Tactical Control Flight.  We are positioned on the radar pad around the TPS-75 sail.  This system replaced our TPS-43. I am first row, centered, with sunglasses. The MSgt holding the guidon is MSgt Paul Williams, acting First Sergeant.  Real old school tough guy he was.  There are too many to recall here, only some of whom I'd have names.
