SpaceX rocket landing 'close, but no cigar'

I'm curious about one of the embedded tweets in which Musk says "Grid fins worked extremely well from hypersonic velocity to subsonic, but ran out of hydraulic fluid right before landing." Then he states "Upcoming flight already has 50% more hydraulic fluid, so should have plenty of margin for landing attempt next month."
Hydraulic fluid is normally employed in a closed system, and loss of fluid indicates some type of failure. In such a situation, one would resolve the loss of fluid, not simply add more. Anybody know anything about this?The first to state his case seems right until another comes and cross-examines him.

Originally posted by lilpixieofterror View PostThe SR-71 leaked fluid, until it went into flight due to the heat it generated as it flew, it sealed up as everything begun to heat up. I'm guessing the same thing, the system doesn't quite seal up, until it is in flight and can begin to seal up better. Before that time, it might leak quite a bit.. . . the gospel of Christ: for it is the power of God unto salvation to every one that believeth; . . . -- Romans 1:16 KJV
