fly-past

Sense: noun/1
All four terms describe aircraft passing for public viewing, but they differ in scope and region. 'Fly-past' (often written 'flypast' as one word) is the standard British term for a ceremonial overhead pass by a formation of aircraft, almost always tied to a royal, military, or memorial occasion — for example, the RAF marking the Queen's birthday. 'Flyby' is the American equivalent and is used in the same ceremonial contexts in the United States, such as a stadium flyby at a Super Bowl. 'Air display' is broader: it covers the full performance at an air show, including aerobatics, solo manoeuvres, and ground demonstrations, not just a single straight pass overhead. So a fly-past can be one element of an air display, but the two are not interchangeable.

Etymology
Formed in mid-20th-century British English by combining the verb 'fly' with the adverb 'past', mirroring older compounds like 'march-past' (a ceremonial procession marching past a reviewing officer). The hyphenated spelling reflects its origin as an event noun coined to describe royal and military aerial reviews; the single-word form 'flypast' is now equally common in British usage.
