Auckland Airport had its second evacuation in two days this morning.

It was unclear why the alarm went off.

The spokeswoman said alarms going off were not surprising as the airport was a busy place.

OK, so let’s work this out then …Auckland has around 10m passengers a year

Frankfurt has around 50m passengers a year.

Five times busier.

So if alarms are a function of passenger numbers, Frankfurt would be evacuated 5 times a day?

And Atlanta (80m a year) 8 times a day….?

I don’t think so, dearie……
