At 33:22, the Stargate opens and an Al'kesh, piloted by Bra'tac, begins an attack upon the Jaffa guarding the Stargate; however, at 33:41, after the Al'kesh passes by the Stargate, the Stargate is seen clearly deactivated, yet Bra'tac still manages to contact Stargate Command and inform them that they are clear to come through the Stargate.
The Earth point of origin, which is supposed to be unique to the Stargate found in Giza, is clearly visible on the Dakara Stargate.
During the battle with Ba'al's Jaffa, a closeup view of an Airman firing an M-60 shows the machine gun's action as rounds are being fed into it via a belt. The cartridges on the belt are clearly blanks as the ends of the cartridges are crimped closed and have no bullets.
