Revelations - S4-E10
Corrected entry: Season 4 Episode 10 - Revelations. When the fleet is just one jump from Earth, Apollo suggests that he and Starbuck go ahead alone on a recon. His father rules this out, but a Commander of his experience would have agreed to the plan to ensure that they did not jump into the solar system and meet a Cylon ambush or a self defence system that attacked them.
Correction: The Admiral has frequently made decisions based on his emotional connections, especially where Apollo and Starbuck are concerned. You can't classify this as a plot hole, just because you don't agree with the decision.
