How droll, and rather ignorant of how freight/cargo operations work. Unless you're crazy enough to drive through a fence like someone did in Fairbanks, no-one will have access to the cargo ramp to even find the right plane, let alone board it to hijack it.
Prime example. At Ontario, the FedEx ramp is on the complete opposite of the airport, where passengers couldn't even get to it.
At Mather Field in Sacramento, the airport is GA and cargo only, with the exception of the California National Guard. Oh, and the airport was a former AFB.
Louisville.. cargo completely separate. Philly: UPS is in a separate part of the field.
If you're going to even attempt to shake someone down, at lest come up with something near accurate. Otherwise, it is nothing but trolling. And you know the rules here about that.
