Narrative:
We entered the cuban fir without contacting cuban control. Reason: fatigue, plain and simple. I was so tired I could hardly stay awake. My required duty rest was interrupted the night before by company. The previous night I had a 14 hour duty day and this day turned into a 12 hour day. This could be fixed by putting some sort of limits on international duty time limits.
