Here is Kristin Dos Santos' (from E!) transcript of the video.
Two pilots are at the helm of a transport plane, maybe a C-17. One chatises the other for clinging to his lucky charm, the one holding the rabbit's foot says he has to be extra vigilant considering the cargo they are carrying. These two are the copilots of a Coast Guard transport that's bringing the Oceanic Six back to the mainland. Michelle Forbes is an Oceanic Airlines rep, strapped into the jump seat immediately behind the pilots. The pilots tell Forbes they're approaching the tarmac.
She goes back into the cargo hold where Jack, Hurley, Sayid, Sun and Kate are strapped in to passenger seats. Kate is holding Aaron. Michelle Forbes tells the Six the press wants to talk to them but she can get them out of it. Jack speaks for the group and says that's fine, they're prepared to answer any questions. Michelle Forbes leaves, tottering back to the cockpit in her stilettos.
Jack says they all know the story, but if they get any questions they can’t answer, the press will just assume they're in shock. Sun: "Jack, we are in shock." Sun and Sayid do like they're in shock, whereas Kate just looks generally devastated. Aaron is wearing an insanely adorable little overall jumper. The plane lands, and the gangplank is lowered.
The Six exit the back of the transport. Mama Reyes, Papa and Mama Paik, and Mama Shephard are all waiting. All three clans are overjoyed to see each other. Sayid and Kate have no families greeting them. Hugo jumps back after hugging his mom hello and introduces Sayid, who gets the full family hug treatment.
Kate, who looks especially freckly for some reason, holds on tight to Baby Aaron and looks around, all alone. I know that Sam Austen is probably supposed to be in Iraq or something (cf the background soldiers in "Something Nice Back Home") and I know her mom is perpetually dying, but she's all alone, and it shows.
