... Concept Spacecraft . ... The proposed lentiular design concept for the Apollo spacecraft was one of several unorthodox designs rejected in favour of the more familiar conical shape which was lighter and less complex.The lenticular design was a ?road not taken?, losing out to less challenging configurations.It is strange to think that if history had proceeded differently, each Apollo crew could have ended their lunar mission by gliding to a touchdown on a runway at Edwards AFB in a flying saucer! ...
