Incidentally, if anyone knows where the video of this can be found, I'd love to know. I saw it two(?) years ago when it was in theatrical release and I thought it was way boffo cool. fred -- ***************************************************************************** ** F.

Newsgroups: sci.space Last week we had an occurrance in the north of the Netherlands. At first the people though it was an earthquake, but the local geologists ruled that option out as the only registered a sound wave and no tremors... Now the experts are split into two camps. One group says it has been a meteorite hit, the othere argues it must been a piece of space junk coming out of orbit. I recall NASA has a dept. that keeps an eye on all that 'junk' up there. Does anybody know if they are missing something that could have come down here?

None have appeared. >-- Henry read the entire thread of what I posted. I agree with you on this subject. My thesis on this is that if you start with a single engine (baby Saturn) with one F1A engine, one or two STME's you get better payload to orbit by over 25% at the same or lower cost because the cost of the labor to put all of those strap ons on and the software developemnt and verification that it takes begins to become a negative factor in the cost cycle of the existing boosters. The labor and engineering costs of a single F1A first stage is much lower than for a HLV Delta or Atlas. AND you design it to take a second engine and stretch tank and you just bought yourself the next Heavy step up with only an increment al cost. We agree on this except that I see the baby Saturn as the beginning of a new class of incremental growth that will eventually drive down the cost of the true HLV when the need for it becomes reality. You simply cannot do this with Allan's HLV Delta/Atlas idea. They are spending the money anyway why not do it in a fashion that plans for the future without driving the costs up today. Motorola did that in 1979 with the 68000 and it worked pretty good for them.
