"Icebound"
The plane was parked at the gate.

...I believe the security is to prevent chaos.

Otherwise organizations like the Ottawa Airport, owed hundreds of
thousands in fees, would attempt to descend on the planes with claims and
try to seize them in lieu of payment.

In Toronto? And, how does the party wishing to seize the plane get onto the
ramp of any international airport? It seems that a single security guard or
police officer would suffice.
