Few of our munitions are now sight guided. This was a JDAM that took a wrong turn on Mujahideen Street.
1 degree = roughly 70 miles, so an error of 1 second of arc in plugging in the coordinates means (70 x 5280) ft / 3600 ~ 100 feet. An error of 1 minute of arc in plugging in coordinates means an error of 6000 feet, more than a mile.
