Fun national alert fact:
When I landed in Italy a couple of weeks ago, Italy also did this loud alarm alert thing at noon.
At this time our plane was just about to land and some people hadn't turned off their phones, so just as the plane was bouncing around, 500ft from the ground, a series of loud alarms could be heard in the cabin and it was terrifying.
Then, hilarious.
5 mins later everyone's phones went off to make an interesting soundtrack as we disembarked. 😁
