Went to make a security round. turned left corner and immediately raised my left arm, to shield my eyes to the unexpected bright, vibrant light. i viewed a arrowhead shaped craft spewing out white, yellow and red lava type material from the right side of the fuselage. first 2 seconds of seeing craft. i could not move. felt someone watching and puzzled why, i knew, it knew, i knew. approx 15-20 mins (of weird time) went by but then, time went to normal. hardest thing to explain is, from the very first time, i saw the craft, to when, it disappeared. it honestly felt like only 6 sec of time had only transpired. only when i finally returned to the guard house. i was able to realized approx 35 to 45 mins had passed, from when i first exited the guard house at approx 0208.
