"The nature of the shuttle was, we couldn't put a crew escape system in it"

Robert Crippen, a previous NASA astronaut and the pilot of the very first space shuttle mission, is highlighting a substantial design limitation of the Area Shuttle in his statement, "The nature of the shuttle was, we could not put a team escape system in it". This quote offers insight into the fundamental threats connected with manned space objectives, especially with the Area Shuttle bus, a recyclable spacecraft designed to transport astronauts and freight to low Earth orbit.

When Crippen describes "the nature of the shuttle bus", he's alluding to the complex and multi-faceted style and practical goals of the Space Shuttle program. The shuttle was developed as a highly flexible lorry, capable of deploying satellites, servicing the International Space Station, and performing scientific research, among other tasks. This multifunctional capability naturally caused design trade-offs, among which was the absence of a robust team escape system.

In the context of spacecraft, a team escape system is designed to securely draw out astronauts from the lorry in case of an emergency, particularly during vital phases like launch or re-entry. For spacecraft like the Apollo pills, this was achieved with a launch escape system that might jettison the crew module far from a stopping working rocket. Nevertheless, executing such a system in the Shuttle was not practical due to its big, aerodynamically complicated structure and the challenges posed by its side-mounted launch configuration.

Crippen's statement highlights the prioritization and decision-making processes in aerospace engineering, where performance, cost, security, and technological constraints need to be balanced. While the absence of a team escape system in the Shuttle was a recognized vulnerability, it was a compromise that the designers and operators accepted due to the program's more comprehensive objectives and technological constraints of the time. The tragic losses of Challenger in 1986 and Columbia in 2003 further highlighted the vital value of safety in human spaceflight and caused modifications in policy and design thinking within NASA and the more comprehensive aerospace neighborhood.
