Jim and everyone with the knowledge take another drink. It has come up again.


Centaur H2 purge line. This part remains attached to the PLF.

That's actually the gaseous H2 vent from the centaur, which is enclosed within the fairing on the 5[0-5]1 variants variants.

It goes directly overboard.  It is the source of vapor coming from the vehicle prelaunch.   It isn't flammable so there is no need to duct it away or keep it away from the sides of the vehicle. Photo is of a WDR
