Filmens originalskript innehåller några användbara uppgifter, inklusive flera scener som skrevs, men inte filmade.
Jag har markerat den relevanta delen:
YODA: Come on - hurry! Hurry!
The SURVIVING JEDI dash to the Gunships and scramble in. MACE WINDU hangs on tight as the Gunship, firing all its weapons, rises out of the arena up and over the topmost rim.
EXT. GEONOSIS, TERRAIN OUTSIDE EXECUTION ARENA - DAY
The massed lines of parked Federation Starships and the DROIDS surrounding the arena, are themselves surrounded by thousands of Republic Starships, disgorging TENS OF THOUSANDS OF CLONE TROOPERS. Beyond, more Republic Starships are landing and spewing out troops.
INT. GUNSHIP NUMBER ONE - DAY
MACE WINDU stares at the incredible sight.
Så svaret är att de klon-trupper som anlände till arenan reste dit i gunships och de flesta trupper som landade, reste sig dit i Republic Starships , som du tydligt kan se i flera av bakgrundsscenerna
