A more thorough explanation:

Definition: To take control of a vehicle or airplane by force or threat, or to steal from a vehicle or airplane while it is in transit.

Examples:

• A group of armed men hijacked a truck carrying valuable goods.
• The plane was hijacked by terrorists who demanded the release of their imprisoned comrades.
• Thieves hijacked a delivery van and stole all the packages inside.

The examples illustrate the different ways in which hijacking can occur. In the first example, the hijackers used force to take control of the truck and steal its contents. In the second example, the hijackers used the threat of violence to take control of the plane and make demands. In the third example, the thieves stole from the delivery van while it was in transit, without taking control of the vehicle itself.
