What status does Independence (FSA) hold compared to Discovery?

Answer

It is a Full Fuselage Trainer (FFT)

The vehicle named Independence, located at Space Center Houston and affiliated with the NASA Johnson Space Center, is technically not an operational, flight-qualified space shuttle orbiter like Discovery (OV-103) or Atlantis (OV-104). Instead, Independence is identified as a Full Fuselage Trainer (FFT). This means it was constructed for ground testing and training purposes rather than for surviving the thermal and mechanical stresses of atmospheric re-entry and spaceflight. Although it is displayed publicly alongside the history of the fleet, its structural qualifications differ fundamentally from the orbiters that achieved spaceflight.
