One of the storylines developed in The Phantom involves the partners' plans for SCDP to finally get that second floor office space Pete Campbell lied about to clients in last season's Public Relations. A quick elevator conversation between Joan and Harry (although Joan denies it) reveals that space has become available on the 38th floor because a parachute company is vacating the premises.
Therefore, Season 5 of Mad Men, a series which uses the image of a falling man as one of its major motifs, comes to a close establishing that there are NO parachutes left in the building. This could be foreshadowing of bad things in Season 6. To wit: The Phantom ends with a montage accompanied by the titular theme song from the 1967 Bond film You Only Live Twice. Dick Whitman/Don Draper, who has already lived his two lives, seems to be attempting to embark on a third just before the abrupt and ominous final cut to black.
