Better get shuttle flying to maintain USA capability

We have Buzz Aldrin, George Jeffs, George Abbey, Al Richardson, DeCastro, Bob Thompson, Charles Harlan, Don Nelson, Crippen & Young,  Eugene Cernan all have written papers or letters saying
Aldrin--Use & Evolve the Shuttle
Jeffs-- Nonsensicial Retirement of the Shuttle
Abbey--paper on " not returning to capsule--keep using shuttle"
Richardson--The Case to Save the Shuttle
DeCastro--On the Early Retirement of the Shuttle
Thompson--My Observations 
Harlan--NASA plan puts America at Risk
Nelson--letter to NASA Adm.--Reusable safer/ more cost effective/more capability
Crippin & Young --should continue to fly shuttle
Armstrong & Cernan Space program Embarrasing--get shuttle out of garage.

All these experts say use shuttle.  Don't go back to capsules and non-runway landings.
Krauthammer said shuttle retirement was inappropriate.
All of these knowledgable people are in agreement, we must continue to use shuttle.
