While talking with Major Lee Adama in the pilots briefing room, Admiral Adama's shirt collar changes from closed to open throughout the scene.
Trapped in an airlock with a leaky seam, Chief Tyrol presses a patch down over the leak, which bulges slightly, presumably from pressure behind it. In reality, with pressurized air inside the airlock and vacuum outside, the patch would get sucked into the leak, not blown away from it.
As Chief Tyrol and Specialist Cally are inspecting an airlock before becoming trapped, Cally looks in a mirror and then moves away from it. Her reflection remains motionless, however.
