Up at 0330 for briefing at 0430. Takeoff was to be at 0700 and just as we were getting",the ship at 0640, they fired red-red flares scrubbing the mission. Came back to the hut, cleaned up and played cards. About 1100, they told us to be at briefing at 1300 for a practice mission. Landed about 1745, had a critique, ate, wrote to Louise and went to bed.
