Crackpot or Visionary?

The errors in judgment of Charles Lindbergh are well known, and they are to be taken into account in evaluating every position he may have endorsed.  But likewise his ability to see beyond what others could see in his time.  He suggested, in an introduction to the autobiography of astronaut Michael Collins, that mankind's next leap forward in exploration of the cosmos might entail freeing ourselves from the bonds of the body entirely, and graduating into pure consciousness.  This is what he said:

Is it remotely possible that we are approaching a stage in evolution when we can discover how to abandon our physical frameworks in order to extend both inwardly and outwardly through limitless dimensions of awareness?  In future universal explorations, may we have no need for vehicles or matter?  Is this the adventure opening to man beyond travel through solar-system space?
