Continuity mistake: In the opening of episode 20, Coulson meets General Talbot in a saloon that is a secret entrance to their hidden base, a base that is many stories underground. Yet in episode 22 Coulson uses his robot arm to call another jet; it appears outside a window! He can't have a window in his office, if the base is several stories underground. And to verify it isn't a "video window" or "projection screen", Mac throws a chair through it, essentially saying "We are above ground, let's go get in that jet in front of us." (00:19:40)

Phil Coulson: You know, it'd be nice, if for once, Thor and his people sent the god of cleaning up after yourself.
Trivia: The call sign for the mobile command center is SHIELD 616. Earth-616 is the name for the primary universe in Marvel comics.
Question: Is there any explanation to how Agent Coulson is alive even after Loki killed him in The Avengers?
Chosen answer: Coulson believes he was resuscitated then sent to Tahiti to recuperate. "A magical place," he calls it. But in the "Agents of S.H.I.E.L.D." episode "The Magical Place", Coulson, through a mind-reading machine, learns that he was treated by S.H.I.E.L.D. and a fake memory of Tahiti was placed as a "mask" of sorts over the painful memory of the operation, which involved a drug seemingly of alien origin to repair the damage, coupled with a lot of morally dubious surgery.
