Why do you need the aircraft waiting on the tarmac burning fuel? Just don't connect the airbridge to the aircraft until the health people are in place. The ground agent has to wait at the first set of doors for the health people to accompany them to the airbridge. Really, the best solution is to have someone talk to someone to talk to the Tower to talk to the aircraft to tell them they can continue to the gate? Please can we amend the Constitution so that the States have to submit to the Commonwealth when there is a national health issue.
