Data Relay: Saturn V umbilicals
-- Thank you to Anderson da Nova for presenting this topic! (twitter.com/DaSupaNova)
-- Umbilicals are connected to the Launch Umbilical Tower (LUT) (JPG: wikipedia.org)
-- From bottom to top, the umbilicals are:
-- Aft Umbilical Carrier #1 - various pneumatic couplings, 8 electrical connectors and a 6" LOX connector
-- Aft Umbilical Carrier #2 - various pneumatic couplings, 8 electrical connectors and a 6" RP-1 connector
-- Aft Umbilical Carrier #3 - various pneumatic couplings, two 4" air conditioning couplings
-- S-IC Inter / "Aft" - LOX fill and drain, and GHe for POGO suppression
-- S-IC Fwd - GN2 air conditioning
-- S-II Aft - Human access
-- S-II Inter - LH2, LOX, vent line, pneumatic/electrical, air conditioning, and instrument cooling
-- S-II Fwd - GH2 vent, electrical/pneumatic interfaces
-- S-IV B Aft - LH2, LOX, electrical/pneumatic, and air conditioning
-- S-IV B Fwd - Split umbilical, serving S-IVB forward section (GH2, electrical and pneumatic) and IU section (air conditioning, GH2, electrical and pneumatic)
-- Service Module - Air Conditioning, vent line, coolant, and electrical/pneumatic interfaces
-- Command Module Access Arm - crew access
-- Bonus: a 360 degree, 25 ton crane (reddit.com/r/space)
