Starbuck managed to get near the Cylon fleet without being detected; she could have nuked the Cylons at that point. This was discussed in the briefing but rejected. It was determined the Cylons would detect the nuke before it could be deployed.
At about 22 minutes, during the close up of the oxygen gauge, the words "Made In USA" were seen on the top of the face of the gauge. Since Earth has not yet been found, this would be an extremely coincidental initialism.
In "Pegasus," both Apollo and Starbuck were transferred to the Pegasus under Cain's command. At 5:22, Apollo's uniform still has a Galactica patch on the shoulder. This error is repeated at 16:30 on the shoulder patch of Starbuck's flight suit.
