Sleep-probe pilots 'failed to answer 11 calls'

The pilots of a Hawaii inter-island flight from Honolulu to Hilo failed to respond to air traffic controllers 11 times as it overshot its destination by 15 miles while flying at an altitude of 21,000 feet.

According to air traffic control tapes obtained by TV station KGMB, a controller monitoring airspace around Maui repeatedly tried to raise the two pilots of the go! flight on February 13.
