IPA: /ˈflaɪpæst/
KK: /ˈflaɪˌpæst/
A flight by an aircraft, especially a military one, that passes over a specific location, often as part of a ceremony or event.
The airshow featured a spectacular flypast by the fighter jets.
Flypast → The word is formed from "fly" (from Old English "flēogan", meaning to move through the air) and "past" (from Old English "foran", meaning in front of or beyond). A flypast refers to an aerial display where aircraft fly in front of an audience or over a specific location.
Imagine aircraft 'moving through the air' ('fly') and 'going beyond' ('past') a certain point — that's what a flypast is all about.
