<P> In Day 4, President Keeler was incapacitated when Air Force One (forced to remain in flight during the current attacks, even though just returning from Mexico) was shot down by terrorists . </P> <P> Despite his initial hesitation, Vice President Charles Logan, under the 25th Amendment, became Acting President, due to President Keeler's condition (he was in a coma). From the very beginning, Logan showed poor judgement abilities . He demanded the arrest of Jack Bauer, which ruined any opportunity to arrest Habib Marwan . When that raid failed, Logan finally realized he was not up to the task, and sought Mike Novick for counsel . </P> <P> Mike Novick, Palmer's former Chief of Staff, recommended that Former President David Palmer be brought in to assist the Acting President . Palmer effectively led the events in the latter part of Day 4, but realized that Logan was a weak - willed commander in chief unable to demonstrate Presidential leadership . Logan blamed Palmer when things went wrong, but took full credit when things went his way . After the terrorists were finally brought down, Logan infamously told Palmer, he "played a role", in the season finale . </P> <P> David Palmer was one of the four people who knew Jack Bauer was alive . He paid his debt to Jack by warning him about the Secret Service agent who was being sent to kill him in order to prevent an international incident with the Chinese (who were demanding the man responsible for the killing of their consul). </P>
