During a televised hearing on February 11, Feynman demonstrated the loss of rubber's elasticity in cold temperatures using a glass of cold water and a piece of rubber, for which he received media attention. Feynman, a Nobel Prize-winning physicist, advocated for harsher criticism towards NASA in the report and repeatedly disagreed with Rogers. He threatened to remove his name from the report unless it included his personal observations on reliability, which appeared as Appendix F. [56] [57] In the appendix, he lauded the engineering and software accomplishments in the program's development, but he argued that multiple components, including the avionics and SSMEs in addition to the SRBs, were more dangerous and accident-prone than original NASA estimates had indicated.

The British Army maintained its requirement for a four-man crew, including a loader, after risk analysis of the incorporation of an automatic loader suggested that autoloaders reduced battlefield survivability. Mechanical failure and the time required for repair were prime concerns. This stemmed from the British Army's concern with the new Russian T-14 Armata main battle tank and the growing ineffectiveness of the ageing L30 rifled gun and the limited types of ammunition supported. It was confirmed that numerous armoured vehicle manufacturers had discussions with the MoD about a potential replacement for the Challenger 2. [27] Shortly after, the British Army decided that purchasing a new tank would be too expensive and chose to proceed with the Challenger 2 Life Extension Project (LEP). [28] The Challenger 2 is expected to remain in service until 2025. [29] Television, Hearst (November 11, 2022). "Artifact from Space Shuttle Challenger found on ocean floor, NASA confirms".

The commander's station is equipped with eight periscopes for 360° vision.
