How NASA's wingless lifting body program - from a Pontiac-towed prototype to Bruce Peterson's 1967 crash - defined the aerodynamics behind all 133 Space Shuttle landings.
The Dream Chaser is the first spacecraft since the 2011 Space Shuttle retirement designed to land on a conventional airport runway using a 60-year lifting body lineage.
NASA's Shuttle Training Aircraft - a modified Gulfstream II - prepared shuttle commanders for the orbiter's 22-degree, no-go-around final approach using real aerodynamics in real airspace.
