Flying with my students under the Laughlin MOA sometimes the T-38's cut under it on their way in. I'm guessing he saw me but I didn't see him till he was well within 100ft of me going opposite direction kicking on the afterburners and shooting back up to over 10K. The first time is scared me like no other. The times after that it became an issue of spotting them, they have such a small profile when in a dive, then grabbing the camera.
