Rockwell’s engineers and designers spent years developing the shuttle’s systems, often working on uncharted territory. The Enterprise served as a test vehicle for these new concepts, allowing engineers to refine the shuttle’s systems before they were implemented in the operational orbiters. For instance, the Enterprise’s design incorporated a delta-wing configuration, which was selected after thorough aerodynamic testing. This wing design was critical for the shuttle’s ability to glide and land like an airplane after re-entry, a feature that distinguished it from traditional capsules that splashed down in the ocean.
Ground Testing
Before the Enterprise could be tested in the air, it underwent a series of ground tests. These included static tests, where the shuttle was subjected to stress conditions that simulated the forces it would experience during launch, orbit, and landing. These tests were crucial for identifying and addressing potential weaknesses in the structure and systems. For example, engineers focused on the integrity of the thermal protection tiles, which had to remain securely attached to the shuttle’s exterior under the intense heat and stress of re-entry.
Flight Testing
After extensive ground testing, the Enterprise was moved to flight tests. The most notable of these were the Approach and Landing Tests (ALT), where the shuttle was carried aloft by a modified Boeing 747, known as the Shuttle Carrier Aircraft (SCA). The Enterprise was then released to glide back to Earth, simulating the final approach and landing phase of an actual space mission. These tests were essential for validating the shuttle’s aerodynamic properties and its ability to land safely. The data gathered from these tests was used to refine the design of the operational shuttles, ensuring their safety and performance.

The data gathered from these tests was invaluable, as it informed the final design and construction of the operational shuttles, such as Columbia, Challenger, Discovery, Atlantis, and Endeavour.
Approach and Landing Tests
One of the most critical testing phases for the Space Shuttle Enterprise was the Approach and Landing Tests (ALT). These tests were designed to evaluate how the shuttle would perform during atmospheric re-entry and landing—a vital phase of any space mission. Understanding the shuttle’s behavior during these stages was crucial for ensuring the safety and reliability of the spacecraft.
Conducting the ALT
The Approach and Landing Tests were carried out between February and October 1977 at Edwards Air Force Base in California. To conduct these tests, the Enterprise was mounted atop a modified Boeing 747, known as the Shuttle Carrier Aircraft (SCA). This unique arrangement allowed the shuttle to be flown to high altitudes before being released to glide back to Earth. The tests were conducted in several stages:
Captive Flights
Initially, the Enterprise remained attached to the SCA throughout the flight. These “captive flights” allowed engineers to observe the shuttle’s behavior while securely mounted to the carrier aircraft. They provided critical data on the shuttle’s aerodynamics and the dynamics of the shuttle-carrier combination.
Captive-Active Flights
In the next phase, the Enterprise was still attached to the SCA but had the option of some limited independent movement. This phase helped refine the control systems and understand how the shuttle would respond once it was released from the carrier aircraft.
Free Flights
Finally, the Enterprise was released from the SCA during “free flights” to glide back to Earth on its own. These tests were the most crucial, as they simulated the final approach and landing phase of an actual shuttle mission. During these flights, the Enterprise’s aerodynamic stability, handling characteristics, and landing gear performance were thoroughly evaluated.
Outcomes of the ALT
The ALT program provided NASA with valuable insights into the shuttle’s behavior during critical phases of a mission. Engineers were able to assess the shuttle’s aerodynamic stability, mainly how it handled during the transition from flight to landing. The tests confirmed that the shuttle could glide safely to a runway landing, a key feature that distinguished it from previous spacecraft, which typically ended missions with ocean splashdowns.
The data collected during the ALT program led to refinements in the shuttle’s design, particularly in areas such as the control surfaces, landing gear, and flight software. These improvements were incorporated into the operational shuttles, contributing to the overall success of the Space Shuttle program.
