David Clark Company heritage IVA architecture adapted for commercial production; designed for crew comfort during multi-hour pad sits
CST-100 Starliner launch, entry and abort survival — Commercial Crew Program
Not EVA-rated; limited public technical specification disclosure as commercial proprietary design
"Demonstrates two parallel commercial crew suit philosophies — Boeing’s heritage David Clark design lineage versus SpaceX’s clean-sheet in-house approach"
Direct comparison case study against SpaceX IVA suit for commercial crew suit design philosophy divergence
Water entered Luca Parmitano's helmet during EVA — vision impaired, comms degraded, breathing compromised
→ Cooling-water management is a primary safety-critical function, not a nuisance issue. Contamination tolerance must be designed in from day one
"Established B.F. Goodrich as the lead US full-pressure suit contractor before Mercury existed"
"Parallel development track alongside Model O testing different mobility solutions"
"Naval and NASA pressure suit research tracks cross-pollinated significantly in this era"
