Working the Frag was harder for the flight leader than for the other pilots. First of all, he had to ask himself how long it would take to reach the target from the tanker drop-off point. He would then call the tanker unit and tell them where and when he wanted to be dropped off. Then he would figure out how long it would take to fly to the tanker and refuel, and that would tell him what his takeoff time would be. He would then give this to the wing ops center, who would pass the word over to maintenance and also “deconflict” his flight from the other flights taking off around that time, in order to avoid midair collisions.

Meanwhile, he would need to look up other information: Who was pulling RESCAP that day? What was the call sign and frequency? Were there special instructions (such as: Avoid Phuc Yen airfield by ten miles . . . so as not to really disturb the enemy)? What were the flight call signs and targets being struck in the same time frame (so he’d know who was in the air when he was, where they were, and doing what)? And what were the code words for the day (such as for recall)? The better the flight leader, the more capable he was in reading the Frag, extracting all the relevant information, and then briefing the flight in such a way that a precise image of the coming reality was created and everyone could fly the mission in his mind before he set out. In that way, when he flew the mission he had already reduced the confusion and fog of war to the minimum.

★ Horner’s and Myhrum’s job was to break out the Frag order, and outline those items that applied to their base: missions, call signs, times for takeoff, refueling, and Time over Target. They would receive the Frag around 2200 at night (it would usually arrive on a T-39 executive jet that flew over from Saigon), with first takeoffs at 0600 in the morning.

In the beginning, the Frag was a nightmare to decode because the Frag team in Saigon would send the entire thing, which was a huge, complex document. Later the planners in Saigon separated out the information that didn’t change (such as tanker tracks, radar control unit information, frequencies, and so forth) into a separate Frag that was kept in operations, and the daily Frag contained only information that was new.

Once they’d broken out the Frag, Horner and Myhrum would give the details to intelligence, so they could dig out target materials, and to maintenance, so they could load the jets with munitions and get them ready to fly.

Once these arrived, the two of them passed the info over to the squadron duty officers, who would wake up the flight leaders so they could plan the missions.

It didn’t take them long to get into the groove of life at Korat.
