Sidwell (b. 1932), the facility operations manager of the Table Mountain Facility, upon his retirement after 42 years of dedicated service to the Jet Propulsion Laboratory. Sidwell worked with the “wind tunnel” group at JPL's Pasadena facility before moving to Table Mountain in 1976, where he has been a source of dedicated and sustained help beyond the call of duty.
