A drone carrying hard drugs, including marijuana, crystal meth, a phone and a pair of hawksaw blades crashed into Oklahoma State Penitentiary, the Mirror reported. The drone suspected to have clipped the prison's razor wire before tumbling to the ground. The prison holds 900 prisoners, many of whom are held as maximum security inmates. Also, the prison has many death row inmates and has its own execution chamber. The use of drones to beat prison security in the United States and British prisons is believed to have increased in recent times.
