As of this episode, the opening narration explaining the premise of the show (ie, Sydney working as a double agent to bring down SD-6) was no longer used. The episodes instead now started with a "Previously on Alias" recap.
At 28:07, FBI Assistant Director Kendall (Terry O'Quinn) tells the team there is a C5 aircraft waiting for them. The C5 is a four jet engine aircraft and one of the largest in the world. Probably a poor choice for a covert operation with a small team. Anyway, when the plane is shown in the air, it is a two-engine prop - almost certainly a C130.
