Past Participle: skyjacked
Skyjack is formed from "sky" (from Old Norse *sky, meaning cloud or sky) and "jack" (from Middle English *jakke, a diminutive of the name Jack, often used to refer to a man or a device). The term originally referred to the act of seizing an aircraft in the sky, hence the meaning of hijacking an airplane.
Think of 'sky' as the place where planes fly and 'jack' as a term for taking control — this helps you remember that 'skyjack' means to take control of an aircraft in the sky.
