were flying, were stealing
Ce jour-là, des drapeaux japonais volaient au vent.
That day, Japanese flags were flying in the wind.
Ils faisaient le poirier, volaient sur le dos et faisaient du vélo.
They did handstands, flew on their backs and rode bicycles.
— Apocalypse Now (1979)
Les oiseaux volaient en formation.
The birds flew in formation.
