Price for an LEO launch of the Falcon Heavy (29+ tonne payload) is just
$94.5 million - Delta IV Heavy is currently $250 million + with a smaller
payload.

http://www.spacex.com/falcon9_heavy.php also quotes a price for "TLI
missions" - why do I get the feeling that Elon Musk want's to be the 13th
person on the Moon... The F9H would get a 3-3.5 tonne payload onto the
surface. That brings up the possibility of something like the Langley
Lander/ Langley Lander Light and a modified Gemini-sized spacecraft.
Interesting stuff!

I've heard mention of a much larger engine for the Falcon series - F-1 power
levels - if this is done, then my Delta V might be better named Falcon Extra
Heavy or similar.

They can compete easily. Spacex's prices are just like the initial
shuttle flight rate projections, not based on any real world
experience.

NASA was quoted well over $400 million for a Delta IV-H. (So much for
cost savings versus Titan IV...)

He has to make a rocket that works first. Any rocket. Just get one
into orbit, and no song-and-dance about how *almost* working is cause
for celebration.

That was before or after the DIV-H was taken off the commercial market?

True; but the systems are in place. Remember that Apollo 8 went to the Moon
instead of being just another LEO test after Von Braun said "there's very
little difference between Lunar orbit and Earth orbit". Once the systems
have been checked out, there's very little difference. Falcon 1s first stage
uses the same engine as the Falcon 9/F9H.

Delta IV-Heavy wasn't marketed commercially as far as I know. Boeing's
marketing was of the Medium variants. The $400+ million is what NASA
was quoted for purchasing launches of planetary missions. They went to
Atlas V instead.

Brian specified 'no song-and-dance'.

In that, Von Braun is quite wrong - the thermal environment is
different, the radiation environment is different, the communications
and operations enviroment, ditto... The difference may not have
mattered much for Von Braun's boosters, but it make a heck of a lot of
difference for the payload.

Ummm. Ok, you lost me on that one - I gather it's an American-specific
reference? A certain (former) politician here in Australia would ask you to
"Please explain".

http://en.wikipedia.org/wiki/Kool-Aid#.22Drinking_the_Kool-Aid.22

From above:

Currently the term is mostly associated with the 1978
cult suicide in Jonestown, Guyana. Jim Jones, the leader
of the Peoples Temple, convinced his followers to move
to Jonestown. Late in the year, he then ordered his flock
to commit suicide by drinking grape-flavored Flavor Aid
laced with potassium cyanide. In what is now commonly
called the "Jonestown Massacre", a large majority of the
913 people later found dead drank the brew. (The
discrepancy between the idiom and the actual occurrence
is likely due to Flavor Aid's relative obscurity,
compared to the easily recognizable Kool-Aid.) The precise
expression can be attested in usage at least as early as 1987[1].
The saying "Don't drink the Kool-Aid" now commonly refers
to the Jonestown tragedy, meaning "Don't trust any group
you find to be a little on the kooky side," or "Whatever
they tell you, don't believe it too strongly."[2] Fox News
commentator Bill O'Reilly is famous for using the term in
this manner. [3]

So, if someone says something like "The Kool-Aid is also tasty", they're
saying that you're buying into what one of these "kooky" groups is saying.
In other words, you're believing what they say without question or reason.

I don't think von Braun actually said that anyway. He said something
to the affect of "once you decide to put men on it [Saturn V], it
doesn't matter where it goes."

And to tie it back, someone who enjoys the "song and dance" is also
likely to enjoy "drinking the Kool-Aid."

Which is true - because the Saturn never really leaves LEO (as an
operational enviroment).
