  DELAYED. No undocking for Dragon CRS-21 today due to splashdown weather! The call came two minutes before undocking commands.

  I apologize for this noob question as I am almost certain this has been answered before, but somehow I screwed myself with the search engine.
  
  Can someone clarify why Dragon 1 wasn't able to return to East Coast for fast science?
  

  "Dragon 1" jettisoned its trunk after deorbit burn, so the trunk came down with the capsule, more or less.  That dictated a West Coast splashdown.  "Dragon 2" jettisons its trunk before the deorbit burn, so no deorbiting trunk to worry about - at least during spacecraft reentry.

• Center of gravity limits are apparently tight.  Huntsville and Houston stressed that multiple times during the late stowage.  The fabric transfer bags, CTBs (contingency transfer bags?) not only had to be placed in the correct location, but the correct orientation.  They have a zipper on 3 edges and hinge on the other end on one side.  All CTBs had to be placed with the hinged side facing a certain direction (dragon starboard) and the end the the zipper dragon forward.  Hard to believe the weight of a zipper on one end or lack of one on an edge (making that side lighter) could be that critical.

  Possibly the zipper is a visual indicator of where the weight is distributed, since the bags are opaque.

• Updated NGA notice removing the splashdown hazard warning associated with today's postponed departure.  All four areas are currently in play for the next attempt.

• CAPCOM updated the crew on results of the U-6 weather brief which predicts Tampa weather as go.  Another brief will be at undock-3 hours...  and they switched to a pink toned external feed...

  The @SpaceX cargo Dragon is "go" for undocking. @AstroVicGlover is monitoring the spacecraft's departure from the @Space_Station.
