Tannoy (Spyfall)
From Tardis Wiki, the free Doctor Who reference
On an aeroplane flying over the Pacific Ocean, a tannoy announced to all passengers, among them two secret agents, that the plane would be descending into Tokyo in another 30 minutes. The tannoy advised through the loudspeaker that passengers take this time to use the toilet or to collect their personal belongings. (TV: Spyfall)
