quickly could the second Island 3 O'Neill colony be built once they
learn all their mistakes from building the first?

Yes. Go here for a spreadsheet model I created:

ZlynmYMAHVIQ6/TangoMan%27s%20Design%20Criteria%20for%20Space%
20Station.xls

find it in there.

Further, go to the website and rummage through the archives in this
their archive.

I did the same archive reading when I joined both groups, and
believe me there is a wealth of information buried in the past! If
you do so, don't forget to come up for air, and happy reading.

Also, go the the NASA Ames sites and Al Globus has put together a
very thorough site. Somewhere in that site are the Summer Studies
that were conducted in the 1970s. Lots of details in those.
