I just reread my reply to Pavel.  I'm not happy with it.  It was too confrontational.  I have a strong opinion that there is a great future for electric powered commercial air passenger travel in the near future, but my reply to Pavel was not consistent with an allowance for someone on this message board to have an opinion contrary to that belief.  My apology to Pavel and to the Hub.   My view, regardless of how passionate that view might be, remains just one person's opinion.  Nothing more.  I respect the fact that there is no reason for me to expect a concensus view on any subject here, especially just because I have a particular viewpoint on the subject.
