Panel 1: Grab
Panel 2: Cracking begins
Panel 3: Sword breaks
Similiar case was going down with Bastille's head:
Panel 1: Grab
Panel 2: Cracking starts
Next panels: Meteorites' already so far down, and Fujitora's reacting out of realization that the bird cage is there.
You could argue the timeframe is far shorter based on the context of
interrupting Sabo.
And unless Fujitora wrote down a cheat code to make a meteorite appear halfway across the sky already, then that meteorite cam down VERY fast, and the POV is of it already being visible to everyone.
