I originated the Single Stage To Tether idea while consulting for Dr. Forward in early I originated the Single Stage To Tether idea while consulting for Dr. Forward in early 1997. I of course did not call it that, and my first stage was a Hypersonic vehicle, not a 1997. I of course did not call it that, and my first stage was a Hypersonic vehicle, not a rocket. The idea grew from multiple discussions with a friend of mine who resides in rocket. The idea grew from multiple discussions with a friend of mine who resides in Raleigh,NC. Raleigh,NC.

I have a 20 year background in space tethers through working with Kevlar and Spectra-1000 I have a 20 year background in space tethers through working with Kevlar and Spectra-1000 earlier in my career as a working cable engineer. I built the engineering materials earlier in my career as a working cable engineer. I built the engineering materials database for Tethers, Inc.(i.e. Dr.Forward), when he knew nothing or very little about the database for Tethers, Inc.(i.e. Dr.Forward), when he knew nothing or very little about the specifics of tether (cable) design. Currently, my name is in the hat with the specifics of tether (cable) design. Currently, my name is in the hat with the HighLiftSystems folks as a lead engineer, should they be successful in obtaining funding HighLiftSystems folks as a lead engineer, should they be successful in obtaining funding for their space elevator concept. I remain interested in any and all concepts that for their space elevator concept. I remain interested in any and all concepts that dramatically lower the cost of access to space. dramatically lower the cost of access to space.
