References?  I can think of several dozen more ambitious robotic undertakings  
that were attempted _and_ succeeded, but of course that's just my opinion.  And  
though I respect the accomplishments of Red Whitaker and his team, I'm pretty  
sure he wouldn't call the Dante project a "minor miracle."

>The failure of the Erebus project.....

But I thought the project was an "[sic] Unqualified Success"?  Or was that the  
telerobotic portion?  (Which, by the way, we've been doing routinely for years  
with basically off-the-shelf technology).

Speaking as someone who has had (too much) experience with fiber optic tether  
failures, I have a hard time believing this statement.  Do you mean more time  
available to prepare for the expedition, or more time on the ice?  Or were  
there other problems of which I'm unaware?  Perhaps you could elucidate?

I happen to occasionally run simulations in my snug office, and actually look  
forward to it after a month at sea.  Of course, though simulations are valuable  
(didn't the development team simulate Dante before building it?), they should  
be followed by experimentation.  However, you and I are fortunate:  not  
everyone can work in laboratories with multi-million dollar research budgets.
