Narrative:
When loading the flight plan. We put in the fix KA12Q instead of KA21Q. We reviewed the plan and mileage and did not catch the error. I said will double check to be sure I don't transpose numbers again. Because the two fix's are about 108 from our last waypoint the mileage is about right. They need to change the fix name. It easy to swap the number and they are too close in mileage to show something is wrong with total mileage.
