- The HL Delta design doesn't use solid boosters on all the
- "core" vehicles... the one I saw had 24 Castors, four per on the
- six outer Delta vehicles. The problem that you pointed out [deleted from
- included text] with staging solid boosters from the "inside" of the
- cluster is avoided by not putting any inside 8-)
- The HL Delta is a neat vehicle concept... it does as reported
- here have a safety margin in excess of 2.0 in all of the new hardware,
- because the designer didn't want to spend $5 billion dollars and five
- years to qualify it. He was figuring an order of magnitude
- less expensive and eighteen months. Probably optimistically,
- but nonethelessvery reasonable. 8-) I had a chance to talk to
- him for a while ... he knew it could be done quick and dirty and wanted
- to do it that way, dammit. 8-) [name escapes me entirely, and I may
- not have written it down... sorry].
