Love the redesigns of the Lightning, HLV-5, PD-32 and PD-64. Particularly like being able to detach the PD-64 and 32 from the LITE stage as you had in your first designs of those vehicles. I do have a question. In the HLV-5A you mention needing to top off the Oscar B fuel tanks in the crew module before attempting a landing. Since you replaced the Oscars with a single tank, do you still need a top off the tanks?
