It was a simple mistake, you guys are being a bit hard on TCAS. He probably wrote it at 3:30 in the after noon, just before going home after a long shift where he had to stay awake all through the day. Those front of the clock office duties are a killer. I bet he was at the end of 5 days straight of the same pattern before his 2 legal days off in 7. We have all been there, fatigue makes you do funny things, cut him some slack...
