- The HL Delta is six Delta first stages connected together (like what was
- done for the Saturn 1B) and three SRBs. No Delta boosters are used. The
- second stage is simply another Delta first stage.

- Since the Delta boosters aren't used I don't think this is a problem.

- The spearation systems are all off the shelf. The SRBs will use the same
- system as with the Shuttle.
-
- Your mental image of the design is incorrect (I think). Imagine two Delta
- first stages (without boosters) bolted together. Call that a Delta cluster.
- Now imagine three Delat Clusters connected together to form a triangle.
- Then put a SRB at the place where the three clusters connect. That is the
- first stage. The second stage is a Delta first stage which fits inside the
- triangle made in the first stage.
-
- I'm going out of town tonight but I have some postscript drawings I can
- post if ther is interest when I get back.

- >Are these considered solved problems, or is that what the proposed development

-
- I believe these where all addressed in the phase I study. I have seen some
- of the drawings and it looks like they got pretty far along.

-
-
- Sorry, the only aerospace hardware I know of with a perfect operational
- record is the HAL 9000 series computers. As of July 27, 1992 they have
- never made a mistake or distorted information. :-)
