Alex Dietrich said she gave an account of what she saw after they landed , I'd guess Fravor did also.
I'm going on a limb to say the Event Summary was their supervisors report on what Fravor and Dietrich had told him.
The "Event Summary" appears to be a kind of standardised report made for every training exercise, e.g. From an air defense exercise later that day:
|FAST EAGLES (BLUE), CAMELOTS (RED), AND HOBOS (BLUE) PERFORMED ADEX IN OPAREA MISR-1E, 2V2. ALL EXECUTED 3X RUNS.|
So the whole tic-tac encounter has been crammed into the "Narrative" format which is usually just a couple of sentences.
This is quoted from the abovetopsecret.com forum where it originally appeared, not sure if there's a better formatted version to link to: http://www.abovetopsecret.com/forum/thread265835/pg9#pid2951082
(Presumably one of those later sorties was the plane that filmed the FLIR1 video, but there's no mention of any such activity).
