Explosive Escape

Exactly two hours ago, the famous American terrorist Johnatan Black, also known as Jack Bomb, managed to escape from the Roca maximum security prison, while preparations were being made for his execution. Jack, however, did not leave without leaving his traditional mark: an extremely powerful bomb, capable of destroying the north wing of the prison complex. You, representatives of the bomb squad, have been called by correctional officers to analyze the tracks and deactivate the explosive. You have only 60 minutes to prevent a tragedy and a mass escape of the other prisoners.
