(Via Today in the Sky):
A go! flight from Honolulu to Hilo, Hawaii, overshot the airport by about 15 minutes last Wednesday leading to speculation that the pilot fell asleep during the 45 minute journey. Mesa owns go! and has had its share of complaints by pilots of fatigue. Falling asleep on a 45 minute flight is impressive, to say the least, considering you climb for the first 10 minutes.
Air traffic controllers tried to contact the pilot repeatedly, but received no response when the airplane passed over Hilo at 21,000 feet. The plane later landed without incident.
