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! ...

... These intense NAU radio waves, after entering the ionosphere in the form of whistler waves, can interact with ionospheric plasmas and excite lower hybrid waves and tens of meter-scale field-aligned plasma density irregularities over Arecib o. The subsequent heating of electrons and ions by the lower hybrid waves is exp ected to yield a chain of ionospheric plasma effects, such as airglow, short-scale density depletion, and enhanced plasma lines in a broad range of altitudes. ...
