Endeavour mission specialist John Herrington talks about transfer operations:

"Well, hopefully, Expedition Five they've packed all the stuff they want to bring home and they've organized all that and they've arranged it such that we can start the transfer process of getting their hardware, the things they brought up with them back onto the shuttle and making sure that we get Expedition Six soft goods and experiments onto the station."

"So we have the time, it's all time lined out as to what gets transferred when, some of the experiments have a time frame that we can, you have to take 'em out and have 'em powered by so we're time-limited on that. It's just a real intricate choreography of all the gear we have to replace -- seat liners for the Soyuz, they have to be replaced, other, they can't change over the crews until the seat liners have been removed and the new crewmembers' seat liners in place. At that point in time, then, they'll have a handover and, this is when they'll, Expedition Six, will be in command of the station."

Endeavour mission specialist Michael Lopez-Alegria talks about transfer operations:

"I guess the official crew swap occurs when we transfer over their IELK, which is a kit that includes their seat liner, which is what is put inside the space capsule, the Soyuz rescue capsule, so, on the station at all times, there is a Russian-built Soyuz capsule that is docked, and it is their lifeboat. So, if something goes wrong -- they get a big hole in the station, somebody has a medical emergency, you name the scenario -- they have to get out of Dodge, they put on a certain type of a entry suit and they climb into the Sokol into the Soyuz and they come home."

"The Soyuz has, sort of, couches in it, and each couch has a liner that is molded to each person's body. It's because you land on, the landing is a fairly sporty event, and it's, you want it to be, you know, you want to support your body uniformly. So, I couldn't fly home in Peggy Whitson's seat liner. So, the swap of that is really what determines which vehicle a particular crewmember belongs on, and that happens on Flight Day 5."

"The other things in that kit are the suit that I mentioned, plus there are survival suits in case they land somewhere and they don't get picked up for a few days and it's cold outside, or if they land in the water, so there are a bunch of different packages that are inside that kit. But once that transfer of the kit is complete, then the crew is officially swapped. Now realistically speaking, that isn't really complete until they've had some time to hand over: to talk about, you know, when you go to buy a house and somebody shows you around the house, and say, OK, this particular faucet you have to turn the knob from the wrong way than you would expect, that kind of thing. And that takes a couple of days as well."
