Narrative:

Military flight took off out of cyqx on apr/xa/99 for moron, spain (lemo). Approximately 2 hours into the flight, a rerte was received from gander. Although the new point was labeled correctly in the mission computer, it was defined incorrectly. The error was not idented until after shanwick oca questioned our position. The crew landed at lemo without further incident. The incident was not reported sooner (within the 10 day grace period) because the crew continued on their mission and did not report the incident until arriving home.
