A Kentucky man who claimed to have a bomb aboard a Los Angeles-bound airliner has pleaded no contest and will serve jail time.
Prosecutors say Lawrence Johnson entered pleas Wednesday in Superior Court to falsely reporting he had a bomb and damaging an aircraft, both felonies. He was ordered to serve 120 days in a county jail, 240 days in a locked-down facility and three years of supervised probation.

You meant where he will spent for 4 months in the county jail, am I correct? I knows this mean for which exact the date for 120 days in jails for trying blow-up the aircraft. So I think he would eventually stay in the jails for quite of long time.
