An incident in the United Kingdom left future flyers with another thing to think about next time they take off -- the possibility that a pilot and co-pilot could both fall asleep in the cockpit. The nap at 30,000 feet appears to have been the result of bad scheduling by the airline. The pilots reported only five hours of sleep over two nights. We inquired about U.S. regulations. The FAA said it made sweeping changes to rules in 2011 for commercial passenger flights, adding, "the FAA does not permit napping in the cockpit of U.S. carriers." Despite the scare flight controls allowed the flight to arrive safely at its destination. The British aviation authority said it's unlikely the pilots will be disciplined.
