Personally I'm more concerned about undeclared Haz Mat and Lithium Batteries (declared and otherwise), to be perfectly honest.
But I appreciate your contribution nevertheless.
By the way, a "ground hijack" in English is technically referred to as a "commandeering".
Example:
"The aircraft was commandeered at the gate but the authorities were able to take control of the situation."
Pedantic, I admit, but this is Pprune after all!
