Cassaro, Robert F., Jr.

Cass flew full-time for the AZANG and after his Misty tour taught F-16 academics until his retirement. At the 162nd Fighter Weapons School, Cass, as Director of Training, “was responsible for the development of the most innovative training program we had ever seen.” His ideas became the data for the Tactical Training Manual for Low Altitude Flight (Miller, 1983, and revisions).”(1)

A story from Phan Rang News on September 25, 1968 tells a story about “Cass”:

TUY HOA – The distance between the antagonists dwindled. Suddenly, their guns blazed. As the distance separating them continued to shrink, the staccato flashes from their gun muzzles punctuated the near-darkness.

As abruptly as they began, the guns stopped firing. Capt. Robert F. Cassaro Jr. pulled back on the stick of his F-100 Supersabre and radioed to his wingman, Capt. Jerry N. Williams, “I’m off the target. Your turn.” As Captain Williams rolled in, the communist antiaircraft gunner on the ground below swiveled his weapon around to meet the new threat.

Captains Cassaro and Williams, both from Albuquerque, N.M., members of the 31st Tactical Fighter Wing, found themselves in the showdown with the enemy gunner during an air strike 16 miles southeast of Chu Lai.
Receiving clearance from the FAC to go for the gun position, the two pilots began making strafing passes with their 20 millimeter cannon.

“Just one thing disturbed me,” smiled Captain Williams. “The only way we could see him was to get him to fire at us. We were diving against his position, opening up early so he could spot us and then concentrating our firepower on his muzzle flashes.”
After seven passes, the gunfight ended. “There was no more ground fire coming at us after the last pass,” Captain Cassaro said, “so we assumed we had gotten him.”
