Crew of the ill-fated STS-107 mission aboard Columbia prepares to lift off

Close up of commander Rick Husband, who adjusts a headset attached to his space suit. He is wearing a full orange puffy space suit and is not wearing a helmet. After adjusting the headset, he puts his hands to his ears and then pulls the microphones in close to his mouth. Cut to medium shot of astronaut David M. Brown, who is sitting in a chair and wearing an orange space suit, but no helmet. He smiles and waves his right hand at the camera. He then puts down his hand briefly, then raises it again to give the camera a thumbs up. Cut to close up of Brown sitting in the same spot, looking to the camera's right. Cut to close up of astronaut Kalpana Chawla. She is wearing a full space suit and helmet, though the visor is pulled up to show her face. She has microphones from her headset pulled close to her mouth. She looks downward as technicians adjust her spacesuit. Cut to close up of astronaut Laurel Clark in a full space suit. Her face is not immediately visible as her helmet is on and her visor is down. She then lifts up the visor to reveal her face. She is looking to the right of the camera as technicians adjust her space suit. Cut to close up of astronaut William C. McCool, wearing a full spacesuit and helmet. His visor is up so that his face is visible through the clear glass of the helmet. He has microphones from his headset pulled close to his mouth. He is looking to the camera's right at first, and has a slight smile as he turns his head towards the camera and waves to it.
