Jeff Wise reports for Wired that a military GPS jamming exercise 100 miles away is part of the reason. The FAA had warned operators that GPS could be affected up to 400 miles away between May 12 and May 18. The controller was busy with three other aircraft that had also lost GPS, and while the King Air waited on vectors, it flew 10 miles past the landing pattern. "When those lights go out, man, you know you are in big trouble," Juan Browne, an airline pilot who hosts a crash-investigation podcast, told Wired.
