Hello Ian G0TEZ and anyone else reading along;
Title "ok" with me Ian. You know me, if I get on this I
usually do a FLIGHT@WW ...but ...oh well;

I guess, here looking back in history, business gets innvolved
as they have the cash and look for future resources, that
travel to another planet would offer?
The Russians seem to have inexpensive ways to do things too, as
that tank they had in space, the old space station, and now I
am at a senior moment not being able to remember the name of thing.

I thought the US, was recovering them now. There was a new report
where the boosters were coming back and recovered in the Atlantic.

Sorry, I have seen few of those on TV, and even wonder how many
were attempted?

That film I would love to see. Will look around here for it.
As for the BOS act...YES...even up until his death my father
was very very conscious of it, and what he said.

How is it, I am not surprised at the above Ian ?

Now you really have me wondering? And looking for the 3 Rocketeers.

have they found a way to improve the engine?

That is a sad footnote of history in those matters. We see it all
the time. So sad. Almost like a backward step.

I'd say so Ian. I also wonder too, if one will need a medical
examination as a pre-flight on one of these craft ? What a buzz.
Takeoff norm. Go into space to avoid the sonic booms, and then
blast to or over where you want to arrive, and your there.
I hope they clean up the space junk fields and other pieces now
floating up there.

Sorry Ian for my deadhead reply. Still trying to see if
that article on a pilot was General Gallant's son.
