How Do Two Pilots Overshoot an Airport?
Pilots of a flight from San Diego to Minneapolis ignored radio calls and flew over 150 miles past the airport. The military was even prepared to intercept. All in all, the pilots of Northwest Flight 188 were nonresponsive for 78 minutes, covering a distance of over 600 miles. With all the attempts to contact them, flashing lights in the cockpit, etc, it is a mystery why this was.
